“Black balling is what it is called when a group of people or businesses get together and deny someone access/employment. So, the boss says...if you don't work overtime with no extra pay or you leave, I will make sure you never get another job. Now, depending on the size of the group, that could be a very real threat. At least for a town, this isn't actually out of the known now.
I am all for a regulated free market. There needs to be a check on business abuses. Collusion, cartels, monopolies(put off my counter post on the only government thing for now, till I have more time), and that isn't the problems between employees and employers, which I think are the lesser ones. Not for unions either, because that kind of allows of employee abuses. We have been doing too little regulation, in my opinion.
Consider:
A group of manufacturers make a deal to artificially inflate the price of a widget. Now, a new company wants to come in and make widgets, and all the current group make a deal to sell them for a period of time below cost, then when the new one goes away(maybe bought by one of them), they charge above what they previously charged and threaten anyone thinking of entering with the history. It is even better if those companies have other means of support. These types of things are illegal under current law. Because it works.”
Okay, all of that is basically talking about cartels and monopolies. Sure, they are market failures, but your analysis failed to consider that most important aspect: government failure, as a comparison point. Sure, there is this issue with the market, but there are even greater issues with government action, because everyone is just as selfish in government.
Companies do far better at driving out competition by lobbying for laws that place huge costs at the door of the start-up company than by lowering prices in the face of any competition. Think about it- if that worked, surely every new product would see a stable monopoly form, since it is even easier to do what you describe as done by cartels.
Furthermore, cartels are inherently unstable. If anyone makes an innovation in their product, they will surely not share it with the rest of the cartel, but rather release it and out-compete their rivals. If the companies engage in marketing campaigns, that is a form of competition, etc. etc. etc. Cartels, when they occur, tend to be short-lived.
Finally, I would just point out that almost every monopoly, and many cartels are directly supported by government. The very worst cartel in the world is OPEC, and that is by governments, not businessmen. I repeat my challenge for you to list 5 monopolies that were not supported by a government
