> People who prefer dense city living with mass-transportation and walkable errands like European cities or downtown NYC/Chicago are missing the fact that there's another group of people (possibly the majority) that actually prefer the suburbs. Yes, I know it seems illogical.

That’s because American cities do their best to make themselves as car-dependent and unpleasant in downtown areas as possible. Of course American college kids want to move out to the suburbs, because American downtowns are not nice places to live. Offer people the choice to live in nice central walkable neighbourhoods like in Europe and they tend to take it.
