This issue has been solved very well in other countries with
medium and high-density construction. Many US communities feel overcrowded because they are low-density.
Yeah I think you're right there, at least to a degree. So many American towns have really crappy zoning laws that limit the amount of high density construction, even though it's awesome for a tax base (especially if you allow for mixed use areas (which has the double benefit of helping mitigate food deserts)).
