It's a good idea, but in some ways, akin to the challenge that would be presented by attempting a similar-veined "why doesn't the world's richest country just hire all the world's best military generals, leaving zero for any other country?".

There's too much diverse heterogenuity built into everything. Including many worldviews and loyalties that go beyond money.
