why they should go bankrupt? The worst case is that they have to sell aplayer, but i thnk teams who don't have expensive Players will still earn alot money because fans are skyrocketing in those leagues(if you compare it with guys who start in fourth or fifth leagues).
And this handicap is not just for a single team, all the other team you are in competion(ok except the cup, but there you still got little advantages i think) have the same handicap like you
