I read the Power Broker  about Robert Moses' obsession of disallowing public transit in the public lands that under his control. That results miserable comutting for New Yorkers nowadays. Bob mastered the political system in a way that he can do obviously irrational things under public eyes, and without any fallout at the time, until the book was published much later after Bob actually has died.
I haven't researched extensively in US public transit, but I am inclined to believe that the public transit were handicapped intentionally through the market operators, in collaboration of the political apparatus.
I could not see any obvious evidence of this particular event being positive or negative. But, I am more sure that the political system in US is crippled to the point that it's not capable of producing long-term positive policy any more.
