Santiago de Chile has an ongoing expansion program for its metro that will add 75 (seventy-five!!) km to its network by 2033 for 7.3 billion USD. It's like adding more than a second métro of Montréal-worth for 50% more of the projected cost of adding 6km to the blue line.

Nonsense. Plenty of people ride transit if transit is useful. The people who need to see a police presence everywhere to feel safe aren’t numerous enough to matter.

There is no way to raise fares to a level that would cover the budget gap because the ridership loss would be so massive.

To understand why US states can be so hostile to the big cities that drive their economies, the location of many state capitals in small inaccessible towns is a major factor. Try shipping a credible sized crowd of protesters from Anchorage to Juneau or Miami to Tallahassee. 1/

Portland is facing dire transit service cuts and we're being told our 30 year old indoor sports arena is out of date and taxpayers must fix it. Transit uses obsolete infrastructure every day. It would be nice to update the rail system so it can run at normal speeds on hot days, for example.

Kansas City was one of the first US transit systems to go fare-free. Now the fares are coming back. The city & transit agency had a choice: Eliminate bus service or charge for trips. They chose the latter. (Low-income riders can still ride free.) Good move. Service quality > Free fares

Americans are being conditioned to think of crime as an urban issue. Ask why. Alabama's murder rate is far higher than New York City's. Urban crime is not worse than rural crime. It's just more visible. In cities everything is more visible. So be careful what you blame city leaders for.
