Actually, that's an incredibly lousy critique.
In Atlas Shrugged, when the industrialists went "on strike" so that they would no longer be supporting the bloodsuckers, they took up work flipping hamburgers in a diner, tilling the soil, working a small mine, building houses by hand, and other menial labor -- which they all considered noble work, and more honorable than making millions "professionally" if those millions were going to be sucked on by the political parasites.
It's remarkably dishonest to portray them as effete snobs who wouldn't know how to cook a meal or who would rely on "underlings" to do such things for them.
