The bands that suck will never make it to the bar/nightclub scene and this is the vast majoritiy of the music base, and thus why the conversation has drifted in that direction. Most are lucky just to get there. You are in different league I guess Irminsul, the minority if you will so be thankful.
Of those who play the night club scene very few will be good enough to ever make it to the corporate, special event scene.
Of the corporate, special event scene how many of these will actually be worthy of commanding large outlays? And the ones who do, are phenominally talented.
Here are the salaries of the those in the New York Philharmonic. The New York Philharmonic mind you.

How many here have attended, let along graduated from Juliard? How about Berkely? How many here have degrees in music? How many here have an albums worth of studio quality original material?
Now what does everyone think they themselves are worth? Anybody here capable of playing for the New York Philharmonic? IF so, you see the pay, guaranteed. Go audition.
I hate to be a buzz kill but this is the deal. If you want to get "paid" these are the credentials you have to bring to the negotiating table.
