Secondly, we can technically afford all this by taxing the rich at the correct level.
I'm not sure what more you want out of these people really. Currently the top 1% of income earners (people making over over $464,682) pay almost twice their share, earning 22% of income and paying 38% of taxes.
The top 5% of earners (incomes over $175,817) pay 59% of taxes despite only making 37% of income.
And once you get down to the top 10% bracket (incomes over $125,195), they end up paying the vast majority of taxes at 70%, despite only making a minority of income at 48%.
The bottom 50% of people (incomes under $36,055) altogether only pay 3% of all taxes, despite making almost three times as much income at 11% of all income earned.
If anything, this system itself is already unfair. You have ten percent of people paying 70% of taxes, and 50% paying only three percent of taxes.
