Because the power of money dominates so as long as PSG has the same resources as today then indirectly their dominance will still continue because regardless of the situation it is difficult to change because to create competition there must be equality and for ligue 1 it is difficult to happen because PSG is too far away in terms of value and their resources that make it difficult for other clubs to catch up.
In Ligue 1, only PSG has good financial strength so they are able to build on their glory. PSG is the only most expensive club in Ligue 1, so it is clear that they can dominate the competition because the squad depth is much better than all other clubs in Ligue 1. The gap in total market value between other teams and PSG in Ligue 1 is very large, so it's natural that PSG can really dominate Ligue 1 in the long term.
I don't think there should be equality in this case, but PSG is required to always adhere to financial fair play in managing its cash flow. Other teams must find ways to provide the best competition, including getting bigger sponsors and investors who are ready to finance the club's needs throughout the season. In this modern era, football has become a rich person's business, but there are still many clubs that have not received generous investors.
Although for this season there are Marseille and Monaco who are still quite good in the chase in the standings but in the end the situation is not too different because PSG is still at the top and other clubs are just following from below.
This season PSG's transition is actually happening especially with the overhaul in recent seasons after Enrique tried to eliminate the Ligue 1 version of galacticos this could actually be worrying, but until now PSG is still quite good for Ligue 1.
It is difficult for any team to stop PSG in their attempt to defend the title, but PSG can still be stopped if the rival team can take advantage of PSG's poor performance in one or several matches. But unfortunately, there aren't many other teams who can take advantage of that, so they will still let PSG take the lead.
