For England, championship teams could spend upwards to 100 million, and if they go up to premier league, they get even more. But here? With that kind of money, you could literally build a team that will stay at second place, if you spend only 100 million a year, then you are going to be second place and that is why investing is a lot easier. Then, you are making an income too, so not like all of it is expense, so not all comes out of peoples pockets. We need rich owners to see how much chance they have here.
Modern football does require funds to build a team although sometimes money is not everything, but in football like today money is very important because teams can recruit players that are needed as a step to make the team stronger. This is what happens in Ligue 1 because PSG is the only club that has good enough finances to recruit many players they want, so the competition there is not competitive because PSG has much better quality players compared to other teams.
Rich club owners are needed to build French football to be more developed and maybe what PSG does needs to be an example for other clubs. This league will develop enough like other leagues when clubs can present competitive competition and that can happen if the teams there can present quality players like PSG.
