How can Marxists preach avenues of personal wealth creation while at the same time preaching that personal wealth accumulation is evil and contrary to a good socialist society?
The problem with capitalism is that capitalists strive to eliminate their competition, and then the dominate the industry, which result in monopolies, that then can charge any price they want to and refuse to provide value to customers. Such as when Pfizer started selling Viagra and had no competition and charged $20 per pill, which is many times the cost of manufacture and distribution.
Another is an example of the very high prices charged for plastics, such a are used for plumbing. A sink J trap probably costs less than 50¢ to make, and costs up to $20 in Home Depot.
Insurance is a huge ripoff for consumers. Banks pay savers under a half a cent in interest, and charge up to 27% in interest to credit card holders.
When there is no consumer control, monopolies and price gouging become common practice and a few individuals end up owning billions while poor children cannot even get a breakfast at school.
It's like a doctor prescribes two aspirin and at the same time advises against taking 100 aspirin at a time.
