They're called "taxpayers," not "revenue sources"

Is there a government official, employee, or lobbyist/union rep for employees who doesn't wish for "stable revenue sources"?

Note this statement reported by Reuters from a lobbyist in California:

"It's been a sort of perfect storm, of a very deep recession hitting us and exposing the weakness of depending on revenue sources sensitive to economic cycles," labor lobbyist Barry Broad said.

California has every form of taxation known to man, I believe.

Yet, this (almost certainly government emloyees' union) "lobbyist" laments "the weakness of depending on revenue sources sensitive to economic cycles."

There is no perpetual motion machine, and there is no "revenue source" that isn't "sensitive to economic cycles."

Those "revenue sources" are called "taxpayers," and their available income varies in direct relation to the economy in which they earn that income.

Government employees could, I suppose, demand "stable revenue" no matter what the taxpayers' incomes are doing at the moment; but that probably isn't a viable option over the long term. Pitchforks, torches, tar and feathers, and split fence rails for the celebratory ride out of town may be out of the question; but our votes surely could be influenced by such a demand.
