Bringing the discussion to the B3 is what is making you blind to this problem. The amount of users that play the B3 is very limited and the managers from former small countries have clearly dominated the competition.
But
new teams in small countries and new teams in large countries are currently playing a different game.
Look at these two teams from Việt Nam:
(207826) playing since 11/06/2009 - Arena 14010 - Balance Transfers $ -3 409 111
(207815) playing since 25/06/2009 - Arena 20000 - Balance Transfers $ -1 550 300
They started last june and one has been able to save 3.4 millions to buy players. The other one has already 20000 seats in his arena.
On the other side, this team of one friend of mine who is very active in the game:
(76893) playing since 15/07/2008 -Arena 6500 - Balance Transfers $ -237 397
He started to play in july of 2008, so almost one year of difference. His economic balance is ridiculous compared to that of the two other teams, and his arena is only 6500. But when he wants to buy a player or hire a staff member he has to deal with those other rich managers.
Of course this game is not only about economy, and it takes some time to learn how the game engine works. That's why they are not yet fully competitive. But if I move to one of this small countries and apply for a BuzzerBeater team, you can be sure that I would be very competitive in 3 seasons or less depending on the time I want to spend. I´m talking about me, but the same for Leyendinha or AlexRepetti. If one of them goes to live to Barbados, you can say goodbye to the B3 in a few seasons.
