The push back on a flat tax is the notion that the "rich" don't deserve what they have and a portion of it must be redistributed to others. I personally don't buy that argument but a lot of people (those who want to receive the redistribution?) do.
If Warren wants to pay more in taxes, what's stopping him? When he files his 1040 he has the option of adding to his tax liability. Let him lead by example if it's so important to him. In fact, anyone who wants to raise taxes can raise their rate without any action by Congress - unless of course they are interested only in raising the taxes of others, and not themselves.
So how about we all just contribute volutarily what we think we should contribute. And while we are at it, how about we earmark what our taxes go for. So conservatives taxes won't go towards abortion funding (fed taxes aren't used for that anyway) and my taxes will not go towards the Iraq war, which did nothing for our safety and only created a whole new generation of people that hate us.
You have no clue how society works. The argument that Buffet should just go ahead and pay more on his own is stupid.
Not just a good idea, but simple common sense. But every discussion I've had with a Republican, they nearly explode their head in fury at the mention of raising taxes back to the level they were in the 90's. They simply ignore their own dire warnings back in 1993 when (Newt even said let Clinton take the blame for destroying the economy by raising taxes) turned out false.
I don't mind someone with a different viewpoint than mine. But if history doesn't prove it out, then shut up.
"Financial capitalism breeds excessive inequality and political corruption which inevitably succumbs to financial crisis and economic depression." Dr Ravi Batra 1990. The only way to correct this inequality is thru taxation of the wealthy to liquidate their ill-gotten gains.
