Yes it does. If it’s actually widely used class stigma dissipates rapidly. See the subway in New York or commuter rail in the New York metro area. I believe commuter rail is also a thing in other parts of the Boston-Washington corridor and I know BART has substantial non-poor ridership even though the Bay Area’s public transport is a complete snafu. North America may have the worst public transport of the continents with substantial development but it’s not uniformly awful, just awful compared to Europe or Asia.
