dude, they are mostly wealthy

I'd be willing to bet that list doesn't include $$$ in trust funds they control.
Trusts, investments, investments in trusts, etc. The reality is that the reason the Democratic congress people are claiming to be advocates for the middle and lower classes by fingering income tax and estate tax is because they aren't going to be paying it, except for on their moderate politician salaries (small relative to their earlier amassed fortunes). Far less barking about capital gains taxes and the relative safety of trusts.
