I think out of everyone I know, you'd have to be the biggest liberal with the strongest anti-Democrat bias. I know lots of lefties who had Biden specifically, but I can't really recall you not sticking the boot in to the Democrat party whenever you have the chance.
I don't think Blackrock, etc own enough to collapse the economy, I think combined they own less than 2% of the total housing market, although they do concentrate in specific areas... but given that supply of housing is so low, I imagine those houses they'd sell would be snapped up pretty quickly.. and it'd probably stimulate those economies as people renovate and spend a lower percentage of their wage on housing.
Personally, since people need a place to live, I really don't think housing should actually be an investment... essentials shouldn't be investment vehicles.
