I really don't understand what you are trying to say.
Are you suggesting it is wrong that one club is bigger than another? That Manchester City should not be allowed to have an average attendance of 54,101 while poor little Burton have only 3,280? That they should not be allowed to reap the financial rewards from that and build a far better team? As far as I know, that has been happening since 1857 when Notts County were founded.
Are you suggesting that every team in football should be equal, with the same finances, the same sized ground, the same sized support, and identical players? That there should be no natural order in the game?
Or are you saying Manchester City should have fielded their U14 side to give Burton a chance? That is ludicrous, and has been identified as one of the major problems with the FA Cup and League Cup.
On that basis, Lincoln would not have been able to play the Everton first team last Saturday. They would have reached the quarter-finals two years ago by beating Oldham U21, Ipswich U18, Brighton U16 and Burnley Girls U10.
And to remove the big clubs from the League Cup would remove all interest. You would simply have the EFL Trophy with a few more clubs playing in it. That wouldn't work at all: it would kill the competition off in one fell swoop.
If Manchester City beating Burton Albion 9-0 in the semi-final of a national cup competition is wrong, you and I must have very different ideas of how the game should operate.
