Then why do they pay so much tax? Top 1% pay 50% of the tax or whatever, and some of that other 50% of tax is actually just the public sector paying tax back, it's not a net contribution.
The other 50%... those people are working!!!! Can't avoid paying people unless we go back to slavery.
Regardless it is one of the rich tricks to borrow against unrealized gains. And other shenanigans.
