There are lots of reasons to dismiss those silly-ass Marxists. Whether because they didn’t realize the USSR failed (there is but one socialism and Reagan slew it!), or because they think history and science are at all correlated. One of the most absurd things that Marxists cling to is the notion of the labor theory of value. Essentially that it’s the application of labor that makes things valuable.
No modern economist with a real grasp of science can ever believe such things. Labor does not create value, but utility. The usefulness of any given item in a market. Here is an example that should shut those Marxists up once and for all.
Suppose a business owner chooses to hire a secretary. A secretary performs a series of duties that result in a more efficient business and therefore higher gains. We economists do not dismiss there is something valuable in such labor, but we do not agree that the mere fact of labor determines value. Let’s assume that this businessman hires a really sexy secretary, some hot little 22-year old with an awesome rack. Then let’s say he tells her that if she’ll sleep with him then he’ll give her a big raise. If she agrees to, which she should (explanation coming), then we can see how utility and not labor determines value.
For one, if we define labor in terms of work done, that slutty little secretary needs to do very little if she sleeps with her employer. Basically, she just has to lay there. And in performing less labor she earns a bigger paycheck, maximizing her gains, and in turn her employer benefits as pulling her away from her desk duties creates utility for him. Marxists cannot account for such win-win situations under their theories. And those quasi-Marxists, the feminists, make objections because they hate the freedom and liberty of letting two equal agents participate in a market exchange. Feminists hinder efficient distribution of wants.
I believe this simple demonstration is enough to prove that free market economics promotes liberty, freedom, personal initiative and utilitarian happiness, all because of marginal utility economics.
