A caste system? are you kidding me. CASTE. Like the system where a group of people were called untouchables??? These kinds of extreme comparisons are so utterly unhelpful to literally everyone.
Frankly just on the face of it your claim is completely out of touch with the US cities with decent public transit options (New York, Washington DC, Boston, Chicago). Everyone that lives in NYC that can take the subway takes the subway. I know plenty of hedge funders and traders and big tech workers in NYC who take the subway every day, and plenty of big law partners who take the DC metro to the office.
Obviously there are really big problems with how transit is implemented and treated in most cities in the USA, but you are completely incorrect. In American cities where there is good transit everyone takes it
