There are advantages and disadvantages to urban and suburban life, and different people prefer different things. There isn't some universal human urge to live in suburbs. The cheap availability of automobile transport simply adjusts the cost benefit by reducing costs, as does racism.
I suppose another factor is that Americans don't really do cities right, but this is largely an effect of the other two factors, plus the awkward way the American political system gives disproportionate influence to people living in less density.
Yes, there are other countries with suburbs. In some of them, the suburbs are more dense and walkable than most American cities, which much better access to public transportation. In others, suburbs are the poorer and less desirable places to live. In fact, this is starting to happen in some places in the United States! It's not just the American 1950's pattern over and over again.
