Look at the graph. Add all taxes- we have a flat tax. With all new wealth going to the richest. That's why the rich love a flat tax.
A flat tax that doesn't begin until 50,000 helps the poor and the middle class FAR more than it helps the rich. Do you know how much more money the lower and middle class would be pocketing? Do you know how much that would stimulate the economy? That's policy that actually helps the lower and middle class. Not filtering tax money through a government that has exponentially increased the nations debt in a mere 8 years, despite record setting tax receipts coming in. Yea that's a great idea.
You're idea of helping the poor is taxing the rich. Government is to act as you're Robin Hood. I got news for you, Robin Hood didn't steal from the rich and give to the poor. Robin Hood stole from a corrupt government over taxing its citizens and gave it back to the citizens.
