I can't speak for other countries, but a normal way of doing this with 1 team is going into rebuilding mode, drop down a league to get a good draft position and to start training new players and not compete at the highest level and save money. Then when the trained players get better, use the saved money to buy some good players to compete for a number of seasons.
By doing this you're able to legally compete at the highest level, I know
(38316) did it this way and is currently ranked #6 worldwide. So even though it might happen, it does not limit you as a fairplay manager.
