BigC, your statism example is something like my friend from Singapore used to say. The best government is a benevolent dictator: no parties system to create waste, no voters to make dumb media-based decisions. Simple decisions made by one singular mind, with the good of all in mind. Heck, the person can even set wages.
Lol, then we wake up. No one exists like that, and if you plop someone into that position, they become corrupt in minutes. And if you define their role to all reaches, no one has that kind of knowledge or real-time information to make such micro decisions for everyone.
Dent is on it, I think. Barter is value. Negotiate on value. If no overlapping deal can be struck that is good for both, then no deal, and move on. And the extension using currency is : You don't want my company's services for my desired price, then move on. If employees don't like the wage, their guarantee that I am paying for value is that they can go work for my competition and put fear in me. If I am not paying enough toward value, I'll then be sure to slice my margins and come asking for those employees if they are so worth the wage; and if I don't do this, competitors will have better staff than I will. The role of government then is to ensure fair competition between companies, fluid information among customers, and fair practices so customers are not stuck with companies and can move freely. And fair competition between the employed, fluid information among them, and fair practices so employed are not stuck with companies and can move freely. No prices need to be artificially set, no wages need to be artificially imposed. Doesn't that work? And the role of government is to ensure freedom... hmm, sounds kind of like the Constitution of the U.S. and of some other countries.
Besides, with what information would government set the fair price of bread? Supply and demand is the only fair way. Forcibly set it too high and companies make too much profit over cost, aren't motivated to work to continuously reduce cost, customers pay too much, and consumer spending is stifled for other purchases and economies suffer. Forcibly set it too low and companies can't make enough money to justify doing it, and either stop making bread or close down. Pricing by natural supply and demand (in free markets, only in free markets!) is the only way to nail correct value.
And same with wages! As long as it's a free wage market, with no artificial barriers to movement, to say Take That Job and Shove It, or to say You Are Not Performing Buh-Bye. The numbers get arrived at by supply of skills and demand of skills. Skills being the total employee, with whatever is required of the job in technical, interpersonal, communication, and team leadership. If a union can collect up a group of workers for collective bargaining, that is good, but there shouldn't be artificial barriers on either end, and union fees must be minimal to fund the administration only and not line the pockets of union bosses. As with products and services markets, a free job market will allow bartering of value between employees and employers. Where a deal can be made, a job is filled. Where a deal cannot be made, an employer is left to redefine the wage so that they can fill the position.
