It is not realistic to be able to tax wealth not kept in the US. Unspent wealth can be kept offshore where it can't be taxed. We want to give incentive to move wealth to America not take it away. That's why the corporate tax cuts are a necessary ingredient in increasing the us's tax revenue.Saving is losing money. People are better off spending it before the value drops out on it.Americans don't have any savings. I think the average American savings is less than a hundred dollars. The Keynesian monetary policy does not allow for savings. Nor does the inflation tax.
It is criminal how government is allowed to rip people off thus.
