If it doesn't make you a libertarian watching a Presidential candidate think "they're just wrong!" is an adequate rebuttal of an entire field of economists, I don't know what will..
If you have a history of terrible money management, and have got yourself into serious debt due to irresponsible spending, no financial consultant is going to tell you the long term solution is "get another credit card".
If you don't fix your spending habits, it will never matter how much money you can take from others who earned it -- you will continue to run yourself into debt, again, and again, and again.
If you can't manage $10,000 responsibly, why would you magically start to manage $100,000 responsibly?
The private sector has that kind of accountability. The State does not.
US National Debt currently sits at more than $23 trillion dollars.
The problem isn't The State not having enough opportunity to tax people, and the problem is not privately successful people.
The problem is a State who can't be trusted to manage the money they have, and show no signs of slowing down.
A wealth tax will do nothing. It rewards public sector financial ineptitude, and the money will not magically be spent responsibly for the first time in the history of Government.
And hey, speaking of Warren! Great time to remind people that she publicly rails against school choice, yet sent her kids to private school. But she's the one to save America from "the elites" ? Sure..
