Munich has the German national carrier (yes, that one, not a state owned flag carrier but you all know the market dominance that brings) with it's 2nd long haul hub. It plays FRA off against MUC, indeed the A380s being moved out of FRA were part of that game. Hence the airport is core to the strategy of a dominant airline. MAN by contrast is a spoke on everyone else's routemap, even Virgin with it's based aircraft doesn't constitute any form of real hub.
Locos like FR and EZY do well but on point to point playing to their strengths.
And given our own equivalent of Lufthansa isn't going to change any of that, muddling through as before is all we can realistically expect.
