What makes me laugh is all these fans are basically saying is, we don't want capitalism.
The catalyst for many owners of clubs is generating money, the glazers saw an opportunity and grabbed it, it's what capitalism is all about.
Yes, we'd probably prefer dirty russian or Arab money, but ultimately that's another can of worms that you could go into about the unsuitability of other owners too. However we've got the glazer family and realistically, they've been decent owners all things considered.
The fans want success but that costs money, lots of it. Players/agents are the biggest leaches in football, their demands increase the debt on all clubs which is unsustainable. The glazer family are only leveraging debt onto the club to keep it competitive. Eventually all clubs will run out of money on the current model, unless their is a wage/transfer cap.
Sadly most fans are thick and don't really get business. They are living in a romantic football world of football from 30 years ago. The game hasn't been for the normal working man since sky injected billions into the game. This is just part of the evolution of football and sport in general. Football is no different to any business or sport really. The truth is, the club will die if the fans want to bleed the club of sponsorship and revenue. The choice is simple, glazers = having a competitive club. No glazers + no sponsors = club in freefall.
