The Bosses and Owners have the money, the property, the machines, and political connections.
And power/money builds more power/money. And because its a boss vs worker arrangement, the worker's power will invariably get whittled down year by year.
The real solution here isnt socialism or communism. Its Worker Cooperatives. This makes the worker = the boss. And the previous conflict between the 2 go away. And the workers can make better decisions with all the information.
For example, when a dictatorial company announces layoffs, it just happens. But losing people also loses knowledge of the company, which is bad long term. In those cases, a worker cooperative could explain the situation, and make a decision together to temporarily cut wages INSTEAD of laying people off.
