The problem with the economy is not credit. In fact, the modern economy simply cannot function without it. Excessive credit abuse is a problem, and people (and business, and governments) should reign in credit to makes a lot more sense.
The problem is not so much the lending of too much money, as the reckless and fraudulent activities that took place after lending too much money.
There's a reason credit was abused. Credit is power - the power to extract payment, to force labor to produce that payment. Default may be an option, but it's never an easy one, so the loan=power equation holds. It's no longer a "company-store economy", but only because now the company store is the whole world! Lend, consume, work to pay off debts - that's how "modern" economists, both "keynesians" and "friedmanites", wanted to engineer the economy. Which is to say, society, and the everyday lives of every single citizen - as an aside, have you noticed that even the word citizen seems to have been replaced in political discourse with
consumer?
There is no reason for this particular organization. Why debt, if it must be repaid anyway? It is a burden and a constraint on freedom, yet propaganda depicts it as something liberating - "go out and buy what you want - now!".
Let's analyze the question. A loan can be used either for investment (business loans, essentially, plus some particular cases of private loans), or for personal consumption. The first type is not controversial here. But the second...
People who have the money on hand to spend will obviously not require a loan (and would lose money if they took one, unless they were using it to free their initial capital to some investment, which would make this a just a roundabout business loan). So the target for these loans are the
people with not enough money for what they wish or need to spend on personal consumption.
Loans for the purpose of personal consumption (and
that includes housing, which is not an investment but a living expense) will be used to buy perishable goods (homes degrade and depreciate) that
create no wealth with which to repay the debt.
The lender is effectively buying the borrower's future labor, his only wealth-producing "asset" which can be used to repay the debt. And I'm not talking just about the obvious case of payday loans, credit cards are supposed to work the same way.
This is supposed to be a form of freedom?! Propaganda can do wonders! Well, horrors, actually.
So, why encourage this? For several reasons.
Because is is in the best interest of those who live off their accumulated capital (profits are one way to do it, but interest can be even better, with almost no work and no risk, usually).
Because it is in the best interest of the "financial industry" - all the people who take a cut from each financial transaction, each loan, each repackaging of loans, each repackaging of packages of loans, each.. you get the idea.
Because those people "own" governments, through corruption and a decades-long campaign to gain influence over the media and the academia. We hold elections in democratic countries, but the political agenda is usually set between these two groups of institutions.
Because "
consumers" let themselves be fooled by the propaganda they were fed, and supported policies which were against their own interests. Namely, the shift of an increasing part of their effective disposable income from wages to loans. Simultaneously they also fell for Ponzi schemes build around unrealistic expectations of profits from stock market
speculation (no, it's not
investment if the money never reaches the company), and even (!) "home equity"! Some might have just wanted dividents, that would be sustainable, but that's not what drew most of the "investment" in stock.
