I never have any problems getting great staff for low wages, it's simple, and when they DO want a lot, it's not a glitch. They simply, want a lot of wage, it doesn't mean the game is broken.
Remember, young and new staff (staff who have regenned or players who have retired) improve drastically if your club is good enough. I signed a seemingly pathetic Australian coach, only 36, his attacking stat was at 8. After three months, it was up at 14, and nearly all his other stats were on the rise. In FM10, one of my players at Villa retired (Habib Beye I think it was...) and I signed him as a coach, he became one of our best coaches within that season, amazingly quick attribute rises.
Try browsing through lesser known coaches and staff (like, just go into the staff search, select Coach [or whatever member you need] and sort by nation) and just check out some of those guys, nearly all of them want tiny wages. I could completely remodel my backroom staff at nearly any team, and pay less than half the wages I was paying before, and have just as much talent in my backroom staff. It takes a bit of time, looking around, but it's worth it when you make a backroom staff made of great staff members, all being paid around 1k a week, compared to the 20k a week each it was before.
