Rail transit is an anachronism, best suited for the 1950s when life involved a woman staying home with the kids while dad took the train into the city for work. I did that for a year before my wife started her job and it was lovely (took Metro North down from Westchester to Manhattan every day). But in a modern family with two jobs in two locations, plus kids with daycare and school and after school activities, it’s not scalable.
My wife and I are “city people.” We really tried to scale the transit lifestyle. We lived in downtown Baltimore for two years and took Amtrak to work each day. We lived in downtown DC and took Metro. We’ve commutes in the Silver line, Orange line, Blue line, MARC, etc. And every year the service got worse, and every time we had another kid the equation got harder to balance. Eventually we threw in the towel, moved to a red county, and bought an SUV that gets 13 mpg. And we’ve never looked back.
You want to know what the future of America looks like? Go to the Dallas suburbs. That’s where all the immigrants with kids are, and where the next generation of Americans are being raised. It’s a glorious place. And it doesn’t involve public transit.
