Let's start with the first understanding, (light) inflation is better than deflation. It causes higher levels of investment, higher levels of employment, and higher productivity. We want (light) inflation, merely because it's better.
There's also a simple productivity bump that can be gained from printing dollars. If someone is unemployed, you can print dollars to get that person to do stuff. If the value of their production is actually higher than their wage, you get no inflation. To get inflation, you need printing past this level. The advantage of the government printing dollars to get stuff done is that governments have a series of investments they can target that would not be pursued by the open market.
Then there's the 'who benefits?' question. If we go with helicopter money (distributed in ways that favour more dollars going to the poor, which I think we've done terribly overall) then the new money favours those in debt. A person in debt can literally hand over the cash, and then free up all the future income they'd have spent servicing that debt. Phrased another way, unexpected inflation can hurt the debtor.
But we're targeting light inflation. This is a bit less harmful to debtors, because the person making the loan will just price in the expected inflation rate in order to get a positive (real) return rate. Inflation only helps the debtee if the inflation is unexpected, and not already built in.
There are lots of good reasons why a country would pursue an inflationary policy.
But now, why inflation is a terrible tax. It's as regressive as all heck. Here's a quick summary why people might disagree.
Okay, the middle paragraph is a production-side statement. Where if we build useful things, it makes people's lives better. It's similar to my second paragraph. We want people building useful things.
I am talking about the tax. Where inflation reduces people's purchasing power sufficiently in order to divert resources to the task we want done. In a real market, I physically take apples from an apple farmer to give to a soldier to eat during the soldiering. What we do with currency changes this simple model. But a tax is literally limiting one person's access to resources with a concomitant increase for another person, because we consume most of the current production
Okay, let's now talk about inflation and its effect on different classes. First off, the comfortably rich. People who like inflation think the comfortably rich person is being damaged by inflation. Barely true. We have a targeted inflation rate. 2% inflation? I don't lend my money at less than 2% nominal, a higher (expected) inflation rate doesn't change the calculation. I buy bonds at 98 with the payout next year of 100. At the very worst, if I cannot find any (real) returns of at least zero, then I'm down 2% on my cash. And only on my cash, every asset I have bought is being subjected to the 2% inflationary forces. On the upside, the rich person is looking for (at least) greater than 0% real returns. So, vastly better than a deflationary policy.
Okay, but wait, the rich are taxed at 40% marginal on the nominal value. I made "$2" last year on my bond, and I am taxed $0.80. So, to get a 'real' return of (at least) zero, I need a nominal return of ($2 ÷ 60%) 3.33%. Unsurprisingly, a higher marginal tax means that the government gets more of my (real) earnings. The inflation ends up being a type of tax. My real wealth goes down, actually down, if I cannot find real returns.
The middle class will have liquid cash. So, any changes in prices will only be a temporary hiccup in the perceived saving rate. Sure, the actual dollars in their savings will be depreciated. They're taxed too. I'm going to estimate that their total portfolio of savings is weighted heavier in literal dollars than the rich person.
But now the lower class. Remember how we called inflation 2%? That's an aggregate, smoothed number. As far as the rich person is concerned, it's merely a number, a yield to achieve on an investment. As far as the middle class is concerned, it's merely a number.
But at the working poor, it's not merely a number. It's not like prices smoothly rise. It's all fits and starts. Remember how unexpected inflation hurts the debtor? There's literally no greater debtor than the working poor. I work. I get paid in two weeks for that work because I'm owed that money. And then bank holds my cheque for a week, before they release my money to me. Same day cheque deposits? Okay, now I am only a debtors for two weeks. But I have literally lent everything. Even if I have savings, I am literally lending more than my savings, in most cases.
And it's all fits and starts. It's all surprises. If I have zero savings, then the $10 increase in a bus pass price means I forgo five burgers. Likely, literally forgo five burgers until my wage rises. Bread goes up 10%? Well, there goes my negotiated increase in savings. It matters, I am giving up something I had previously expected to purchase. All price increases are unexpected. Any changes in price hit at 100% pain levels. And Lord knows what happens if I need to borrow in order to handle an unexpected price increase.
And it's regressive all the way down. Businesses operating at close to the margin need to deal with unexpected price increases too.
Now, let's go to production-side thinking.
We have two burger flippers, a better-paid live-in house-keeper, and a person who's rich. Everyone can eat burgers, and all the burgers are eaten.
Now you want to initiate a new project with printed dollars. And you're printing enough to cause inflation.
To woo someone from flipping burgers, you pay that person slightly more to come build a bridge. What happens? Well, in the short term, we have fewer burger flippers and we have three people that are better-able to buy burgers than the remaining burger flipper. Any drop in supply will be borne by the weakest of the group. And supply is permanently reduced, keep in mind, we're at full employment. The increase in price that the builder will pay doesn't encourage new production be brought online. The price just goes up. The fact that a bridge will happen in the future doesn't change who's paying. The fact that the poor are best benefited by the bridge doesn't change who's paying. The increase in supply from the new project will (necessarily) come later than the decrease in current supply, since the project is an investment designed to produce returns. If the project instantly decreased net prices, it wouldn't cause inflation.
There's also a simple productivity bump that can be gained from printing dollars. If someone is unemployed, you can print dollars to get that person to do stuff. If the value of their production is actually higher than their wage, you get no inflation. To get inflation, you need printing past this level.

But now, why inflation is a terrible tax. It's as regressive as all heck. Here's a quick summary why people might disagree.
Inflation isn't regressive, because people at the bottom don't have significant cash savings. Unless you count price-anxiety as a cost. I suppose inflation reduces the minimum wage where it is set by legislative fiat. But progressive where there is rent control.
You have to look at where the the money is coming from that causes the inflation. Building infrastructure and maintaining bus lines and train lines and credits for rideshare means the cause of the inflation is in people getting paid to do those things. That's some bottom/middle up stuff. That puts upward pressure on wages, the sole source of wealth for anyone below the top. The supply-side of the inflation would be on the materials needed for those things, if we are already at capacity. But if we are not, then even more industries will see more employment (the gathering and processing of materials).
Please understand that general inflation is generally progressive, which is why the only parties supporting inflation as a policy have been progressive and populist parties.
