Earlier quoted context omitted.
It also needs a much bigger emphasis on transit oriented development. In Japan the best place to eat in town is often in the train station or within a few feet of it. In the US the stops are often some of the worst places like parking lots or run down parts of town. Rarely have I seen good shopping/dining/living integrated into BA, or even US in general, transit systems.
My office in Cambridge, Massachusetts is directly in a 12 story tower with ground floor retail directly on top of a transit station. TOD does exist, it’s just rare for whatever reason in NA. That said, there are lots of other stops in the area that are either overrun with parking, like you said, or are one story business districts with no housing. Lots left to do. I suspect the problem might be mismatched incentives.…
That station (the Google Office MIT/Kendall one I'm assuming) was part of the larger redevelopment that happened in Kendall Square over the last 40 years which displaced a significant portion of Cambridge residents due to eh flawed 1949 Urban Redevelopment Act (the same one James Baldwin historically opposed).
Just go one stop inbound (MGH) or outbound (Central) and that level of synergy goes away.
A lot of this is because the T is just straight up old. Most of the stations are at least a century old if not older and it would take an inordinate amount of money to rebuild stations in a more modern manner.

The Asian as well as the more recent North American metro systems like BART or DC Metro are much newer (built or rebuilt in the last 50-70 years) and were thus able to include that public-private mixture.
