Or they'll just start talking about the profits exploited being fair compensation for the capital risked by buying, owning, maintaining, and paying for the means of production and other cost overheads (rents, utilities, fees, expenses from networking, permits, advertising, insurance, legal costs, property rates, conveyancing, taxes, logistics). Arguing that what Capitalists put into their business (and providing others a place of employment) is so great that they get greater rewards for success, and harsher losses for failures.
If a business goes under the worker merely has to switch jobs, a boss may end up with a significant loss of status, and wealth, as well as retaining debt.
So I think the propaganda elements of the Capitalist class aren't so necessary, as there are arguments they can try to make against Marxism.
Anyways obviously I'm just demonstrating some of those arguments... And not making them myself, or looking to defend them. I'm more interested in whether others can see, construct, or remember arguments they know which defend the Capitalist class. Knowing your opponent sharpens your reason, and prepares you.
