Twenty years from now, especially is the US was to land to 2022 or 2026 World Cup, MLS could be up there in terms of talent due to the amount of money potentially available to attract the best in the world not only from the US and not just those on the downside from Europe to the US should interest continue to grow. I can see the US just behind the current Big 3 (Germany - Bundesliga, Spain - Liga, UK - Premier) and at or slightly above the next tier (France – Ligue 1, Italy – Serie A [sorry; but the recent scandals have cut down most of the Italian clubs outside of Milan and Juventus]). But for now, absolutely, to beat the best on the World Stage requires who play the best on the world stage every day and that means US players need to be on and start for teams at that level.
