Earlier quoted context omitted.
Europe and USA are both huge places so it depends what you mean. If you compare major east coast cities - Boston, DC, and NYC to European metros like Paris/ Madrid/ Lisbon the biggest tax on the citizens is the same in that it’s impossible to build anything so a huge % of income needs to go to housing.
East coast cities were built before modern building codes. Something that, for some reason, people in the states don't want to accept is that - when given the choice - the vast majority of people prefer living in dense urban environments.
The vast majority of people REQUIRE to live NEAR their employment which happens to be in cities.
Look what happened to NYC real estate rent when you gave people the choice of NOT doing that. Look what happens when you force them back to the office, they come back, but not by choice.
