Would Basketball in the US be better If they switched to a system and culture like Europe?

For example like Player development:

Would It be better for Players to play for Academies instead of High Schools and AAU Clubs?

Another Example: Should there be a league system with multiple divisions that involves regulation and delegation?

Like NBA would be 1st tier

G-League could be 2nd tier

TBL could be 3rd tier

Then there would be smaller national leagues and regional leagues
