On what do you base that?In the US the rich - often - are not paying their fair share of taxes. The biggie I see is that they tend not to pay for their companies' use of the infrastructure. Roads, the grid, schools, police, fire, and so on. All of which they use to their benefit.
Here in MI, business properties pay full property
taxes, unlike homeowners, who get discounts
of 50% or more. Also, my commercial properties
have been often assessed at above market
value.
You mention schools. Businesses pay more per
dollar assessed value than homeowners, despite
having no children in schools.
