There's also a large lobby group that is fully invested in building new houses, namely real estate developers, and since most politicians at a high level usually need large campaign contributions, they are fully invested in it as well.
I think I've heard everything now.
(In fact, my local government is actually closing roads near new housing because "f#ck cars" is apparently a hip idea these days.)
I'm saying that developers are eager to build housing and sometimes are able to cut corners via undue influence over public officials. That leads to more housing (good), but it also erodes the quality of life for residents (bad).
It's really not that hard to understand.
