I think it probably is, in a way. I think when Roger wrote it, that's one of the things he had in mind, since that is the general direction of his politics. But more, I believe Rog meant to ridicule the wealthy (of all stripes) who place their love of money above all else, making it their god. True, there are likely more rich capitalists than rich socialists (except for the Hollywood left, and a-holes like Ted Kennedy who inherited his wealth, but feels so guilty about it that he wants to give everyone else's away).
I believe a monetary system is an absolute necessity, regardless of the political, social or economic system in force. Think what a pain-in-the-ass it would be to have to barter for everything.
Tark, how would the Trotskyites handle that? Does the State come by the people's farm and pick up your potatoes, and drop off all the other life necessities? Or do you just go stand in different lines to be given what you want?
Bottom line, I believe Roger was just listing the struggle to earn a living (money) as one of life's problems we all have to deal with.

P.S. Maybe if Roger would have written it purely from a Trotskyite perspective, it would have been called "Potatoes."
....Potatoes.......get a-hoein'....pick out a row and hoe, keep a-goin'.......
