Warren has that silly idea of a "wealth tax".
Why exactly do you consider it 'silly'?
A significant number of wealthy people pay little or no tax because they don't have 'income' in the regular sense. The gini coefficient (which measures wealth inequality) in the U.S. has been increasing steadily. The U.S. has a huge deficit and needs to upgrade certain infrastructure.
If not a 'wealth tax', what do you suggest the U.S. do to handle its fiscal problems?
