Yes, the institutional investors aren't going to be in your local council meeting. They will be meeting with your state assembly members. They will be meeting with your Congresspeople. They won't be literal NIMBYs focusing on anyone's "backyard". However they will be working towards the same goals at NIMBYs, just at a larger scale.
It's amazing the power those subjects have to turn "YIMBY" into "regulate me harder daddy".
The cognitive dissonance required to enable this about face is a bad thing and seems to be becoming more and more prevalent and accepted in all sorts of public policy contexts.
Now lobby dollars are another story. But renters can fix that by actually voting.
I don't know of any local councils that grant local votes to anyone -- they vote themselves. This should spark an idea of how rich people's dollars outweigh poor people's input. They only have to convince half of the council to vote one way. This can be done through wining and dining, sending "experts" to make presentations, making promises, and so on.
Local to me, we've had a few causes pop up with surprisingly well-run NIMBY efforts opposing them in recent years. The amount of money raised and the signs and slogans are way too good to be the product of the actual locals who speak out on behalf of these groups - somebody else is clearly funding them and doing some marketing.
Go to a planning meeting about some housing that people are pissed off about because reasons ( https://news.ycombinator.com/item?id=32569768 ) and you'll find a whole bunch of your neighbors. It's not institutional investors blocking this stuff, by and large.
> they are worried about the value of their own home going down. They are treating their home primarily as an investment because that is what they have been told to do their whole lives
Yes, that's much closer to what I've observed in person fighting these fights.
