It’s unethical and plain wrong. In which other industry are the main players protected from competition? If a business manages to attract large financing to grow, then how can you prevent it?
If the powers that be really wanted to be ethical and protect sporting integrity then they would apply the rules equally for all. The bigger clubs already have a big advantage due to their popularity, shirt sales, etc. around the world, especially Asia.
IMO we will get there although it will take some time. My reasoning for this is that football is corrupt as f*ck and we are very rich!!!
