Suburbs are pyramid schemes that are already beginning to collapse. Infrastructure costs are unsustainably high without density and plenty of cities are going bankrupt when it comes time to replace sewers etc.

It's funny that you mention infrastructure. Do you know that one mile of Manhattan subway now costs more than 1000 miles of modern 6-lane freeway?
Suburban infrastructure costs are in line with the _average_ urban costs (some cities like NYC or Seattle have _wildly_ inflated costs). Some costs are slightly more, some are less.
