There is no "spirit" of the World Cup. It's a business venture run by business men to make money. FIFA is a business venture run by business men to make money. Professional sports is a business venture run by business men to make money. Even the Olympics is business venture run by business men to make money.
Unlike you, I know that foreign-born players are necessary because because the business men running footie teams to make money use whatever foreign-born players they can afford. You can bleat about the "spirit" of the game and what is "fair" all you want, the bottom line and the actions taken daily by club owners to protect and grow that bottom line is all the proof I need for my assertion.

Eh? The FIFA may be run like a business but it's a Federation of football associations. The members of those associations are almost always clubs, not business or property.
