Title, basically.
Where I live, 'suburbs' = not the city centre, detached/semi-detached houses with back gardens & sometimes small front gardens + 2-3 stories, sometimes terraced housing as well, and alrightish public transport. It's where commuters live who travel half an hour to an hour to get to work.
Any discussion of American suburbs is all about how they push out black folks, are a huge waste of resources, etc. I don't know enough about America to have an opinion but I feel like I'm missing something.
There's a lot shit tied up in suburbs. For one, there's this post war economic motivation of building shitloads of single family homes for returning soldiers. Expanding out of the cities so white people could get away from minorities. Car culture. An anti-communist/By your bootstraps ideology of creating a world where the nuclear family is the only social unit, and consumption is the only activity that can be undertaken. So much different bullshit.
