That is the big flaw of USA, it really punish people for situations outside their control. It would make a lot more sense to raise taxes for people making $100k by $10k and use that money to help the people that need help, by like removing childcare, healthcare and college cost from the individual and make it tax funded.The average daycare cost for the state of Washington is somewhere in the area of $310 per kid per week. If you are a sole income earner making 100k a year and you have two kids going through daycare, you’re looking at somewhere around $30k/year just for childcare (i.e not including food, clothes, diapers, etc.). That’s 30% of your income just in childcare. If you have a car payment, and/or high rent, and/or medical or student debt, then your effective available income is going to be pretty small even though your gross income is high. That would of course increase even more, say, if your spouse was long-term unemployed or chronically disabled, or if your or their parents were living with you and also had chronic healthcare or hospice care expenses. You can very quickly get into the effectively living in poverty range. Even without the extra dependencies, you are still extremely precarious: one missed paycheck, one car wreck, one major health emergency for you or your kids, and you are facing serious, long term financial crisis.
