My thought is that 1% of income over 1mill isn't all that much, and moving would cost them much more than that. Also, I haven't heard anyone offer any suggestions as to where else to get the money.

In addition, they will get a return on their money from less people on the street or in high cost inpatient care, and just because they are rich doesnt mean that they or their family wont need that kind of care some time.
