What are we doing about the appalling quality of construction in the US? My in-laws live in a pretty standard 1960's midsize apartment building that went up when Lisbon expanded under Salazar. You really can't hear the neighbours because it was build in concrete with proper sound insulation. The stuff that you see built nowadays in the US is still matchstick and sheetrock, of course no one wants to live in conditions where you can hear everything that's happening on the other side of the wall.
