Let me take exception to one category that you mentioned, which is multi-generational.
We have the severe problem that there are people who can't afford a place to live. Now, on vacation communities, of course, you can raise issues, but if I inherited a lovely place on a lake from my father, who in turn, inherited it from his grandfather, I don't know why that makes me a particularly sympathetic person. Usually, when we think about who needs the government's help, we focus on people at the bottom of the income distribution who have been unfortunate.
I hate to bring this up, but multi-generational, for me, does not trigger sympathy. It triggers, “Okay, you have to pay $1,000 to $1,500 a year in tax for the house you inherited for nothing.” It's not the end of the world.
