Because something might benefit the bourgeoisie as a class(God, forgive me for using Marxist concept of class), does not mean it makes sense to do individually, which is what we were talking about.

But I would say this is exactly backwards: individually, it always makes sense to pay less if you can, but not in terms of the whole economy.

Even if you think in terms of macroeconomics, no, poverty is not beneficial. Any economy needs a strong market to sell goods to. Unless the country is exporting somewhere else, high amounts of disposable income is needed in the population for a thriving economy. Paying workers less does not necessarily result in worse outcomes for businesses, especially in the long run, since the economy might suffer.

So you could say that the statement "the bourgeoisie as a class benefits from poverty" is incorrect.
