Most of 'em deserve it, though.
They deserve where they are through their own failures (I assume you're referring to the likes of Leeds), they don't deserve to be playing against reserve sides every week - just like Conference, Conference North/South and as far down the pyramid you'd care to go don't deserve it.
Not even comparable to Spain tbh. I like Spanish football but our smaller local, lower league clubs have better away following than their top flight clubs ffs. These teams are the hubs of their communities. Our league system has functioned perfectly fine for over a century and we don't need to start messing about with it because the self-serving rich teams want to as it suits them.
