Older US cities (Boston, NY) have great public transit/walking options, though I agree deferred maintenance is taking its toll. But if you look at cities designed around the car, for many of them it's just prohibitively expensive to add things like light rail or subways now. Austin TX will be adding more light rail, but the price tag keeps exploding and the route keeps getting shorter.
I'd be curious if anyone could point to any city that was built around the car where they subsequently made substantial public transit improvements that carry more than, say, 10% of commuters.
The "more funding" is always allocated towards existing rent-seekers.
And my opinion with getting junk is that if I'm getting it, I want to be paying as little for it as possible.
As a quick test for what you feel, try this. You read a headline that says "This city school received the most government funding of any school in the US". Do you think that school is "great" / "mediocre" / "crap"? My personal immediate inclination is that the school is probably shit.
