I think it'd be most interesting if all teams had sort of an equal start every season, and as such the stars would be divided a little more over leagues and clubs. Then tactics and managing your talents will become more important than marquee signings and overpaying your competition into a weaker side, to stay strong as the Bayerns, Reals, Citys, (but also Uniteds), etc. But with the elite being the way it is and has been before the rich ownership/investors/sponsors, that's not going to happen.
So things being the way they are I kinda am not going to check the background of it all anymore. Also, in FIFA or PES I occasionally increased transfer funds to create a star side, though that bored way quicker than building something up (NO I DID NOT SECRETLY CHECK WHO DEVELOPS INTO CERTAIN STARS ONLINE), but it did make me feel like there's some truth to the 'interesting project' statements when players join the richest of clubs. Even if United was a star club earlier, them and the quick-rise-rich clubs are star clubs now too. Joining a team with De Bruyne, one with Neymar, one with Ronaldo, one with Pogba, does sound like something a lot of people want to experience, especially since it's easier to be excited when following teams challenging for titles than the more abstract concepts of Conference League play-off positions.
It's also that I follow football way less than before, so it seems extra unnecessary for me to think and read about how the big clubs of today or tomorrow got to where they are. I follow Atlético, and to a lesser extent I follow United and a few other clubs when I feel like it. The lesser extent clubs are based more on their squads than is the case with Atleti for me. So if PSG put together a team that's put together nicely in a tactical construction, that make me want to play with them in PES (or the like), I'd gladly watch the occasional game. Overpowered players/teams kinda turn me off, though (I've got pinches of hipster flowing through my veins), and for some reason Messi's playing style doesn't do it for me, even though his dribbles, finishing and throughball passing are so so good. So, I don't think I'll play with them. But the idea is nice and the highlights reels could be great, too. But the type of Pogba (it's probably also why I'm more lenient with him than people who demand more consistency), the type of Greenwood, etc, make me enjoy following Man Utd. Just because United is rich and in a privileged position where their horrible spell didn't kill them, doesn't make me hate them. What it means to earn that security through past successes, I don't really know, but for the right now I am glad to have a Man Utd around, and some of the rich clubs provide nice squads that have widened the groups of challengers in the Premier and Champions Leagues.
Whether any of that is fair or not, I don't have the energy to care. Heck, I even wonder where I got the energy from to write this rubbish about it from.
