The UCL itself is a manifestation of this. Clubs who play in this competition get additional revenues that clubs who don't play in it don't receive. Those revenues can be used to purchase better talent (in a league with no cap on salaries or transfer fees), build better infrastructure, marketing, etc. which increases the likelihood that those same teams will be in the UCL the next season. This is just a more extreme model favoring the big boys. The UCL is a thinly veiled attempt at parody while this is in-your-face what the system is really about.
