There are a lot of basketball players for example from the US who play in Europe because they didn’t get into the NBA. Also a lot of Volleyball players (especially female).
Why don’t the US make more leagues for their own athletes? Like 30 professional sports teams per sport isn’t enough for such a big country, right? For example, England has a population of just 50 million, but they have 5 pro soccer leagues with much more than 100 pro soccer clubs.
The US has 350 million people, but much less pro teams in the respective sport.
Why?
