You've already spent a lot of time to raise the fund, unpaid or paid out of proceeds from a previous fund first. Then you have to put in a massive effort to find, sort through and vet investments. Either there are quite a few of you, or you have a nightmare work pressure for several years unless you already have a massive rep (and it's still work).

And most LP's will expect the GP's to have significant skin in the game. E.g. at my previous employer, every staff member was expected to have at a minimum the equivalent of 1x gross yearly salary committed within a few years.

VC salaries are not that great outside the top tier funds or unless you're one of the GP's.

It could be "retirement money" for a handful of the GP's at the top tier funds, but they're only in that position in the first place because they have a lengthy track record, and so their past earnings from carry etc. will still dwarf any operating fee from their current fund.
