You're leaving how a key part, at least in America which is racism. Whites ran to the suburbs to escape particular groups and quite frankly still do albeit now it's more in the form of urban sprawl.
This is BS. People go to suburbs because they want a nice house, not because they are trying to run away from race. I grew up in a mix-race suburb. I loved my houses and my friends houses. We had great times on our cul-de-sac since it didn't allow through traffic it was safe to play in the street. We loved our backyard pool. We loved our garage that had a radial saw and a large tool desk. We loved our large 30x20ft family room where we had large slumber parties and large family parties. It requires zero racism to want a house in the suburbs.
Historically, suburbs absolutely were motivated by racism - it's called "white flight".
Today, it usually isn't about racism, it's mostly just continuing status-quo trends without question. But it's important to not put the initial motivation of those trends up on a pedestal.
Plenty of other data shows the same thing. Racism is very much a part of what built suburban america in the large even if it doesn't apply to you or your family personally.
