It is highly immoral for any individual or govt to decide they should confiscate that wealth to use it to fund their own preferred projects, items, desires...
That money is used to buy things which supports jobs/economy, to invest, which supports jobs/economy & for charity.
As the pie is not fixed in the US, the wealth was created & is not at someone else's expense.
And if you didn't have people creating wealth and expanding the pie, there wouldn't be the ability to even spend at that level w/o more debt.
