One of the best jobs I have ever had was with a really decent manager (and decent human being). Formally, she was the manager - in practice she covered us, ensured that as long as work was done we did not have to pretend to be working during quiet periods pointlessly and fought tooth and nail from her position to ensure we were decently treated, had proper breaks and decent equipment. She realised our jobs depended on our working well as a team.
The worst jobs I've had have involved crap managers as much as crap bosses. Arseholes who simply passed on orders rather than negotiating them (up or down) and never dared to put in the practical requests (usually health and safety based) we asked for.
As long as you are a decent rounded human being with a reasonably good grounding - that can keep you grounded if you do come under pressure to be part of any crackdown - in the reality behind daft hierarchies you could well be a decent 'manager'. Just try and remember how its like for those looking up at you
