How many people, if afforded a competitive salary from rival institutions, would choose to live in Turin or Manchester over Paris? Not many.
The notion that top players are only choosing to play in Paris for economic reasons, as if Europe's traditional elite can't offer competitive contracts is silly and juvenile.
Spoken like someone who's never played football professionally, competitively, or otherwise.
Fact is Ligue 1 has been weak post Bosman ruling because it made it impossible for French clubs to compete financially with clubs from England, Italy, and Spain. See Ronaldinho's transfer from PSG to Barca, the spark that lit the fire that became FC Barcelona's current dynasty. But now that investors(QSI) are pouring money into the league to change this dynamic people like yourself are unhappy, because you no longer get the pick of litter when it comes to stars and or developing talents.
My advice would be to get over yourself. Players have to obligation to choose to play for FC Barcelona simply because it's FC Barcelona. The world doesn't revolve around you or your club, so if you want top players to wear your colors over the colors of rival institutions then you have to do the work. In this instance, you did not, and you lost out. That is no one's fault but your own.
From what I've read on r/soccer Ajax fans prefer him choosing PSG over Barca because of the arrogance of the latter supporters throughout this transfer saga.
