Public transit is one of the few public spaces we have left, ironically. Perhaps especially so post-Covid. I think that it's worth the investments necessary to make it usable. You can't blame public transit for the lack of effectiveness of homeless programs, and some folks are homeless by choice. It's a fraught situation, and that's why folks choose cars a lot of the time. It's more convenient for them and I guess I don't fault folks for that, but the built environment shows a lot of deference for cars in many metro areas, and that doesn't help with the traffic issues, or with zoning issues, or with housing affordability.
Yet, if you improve those other issues, then property values will probably just go up even higher than they already are, but at least that money will benefit more than just the buyer and the seller; it will benefit the entire community.
