as someone who owns and runs a few companies, the largest having around 1000 people working in it, I can understand why some people, especually who never built a company, think that the people working for a company are underpaid compared to the people who buolt it. This misunderstanding is easy to develop, people (and many other animals) have a strong built in mechanism responsible for having emotions and feelings related to fairness. This expectation of fairness is easy to channel into a different sort of a feeling - expectation of equality, feeling that equality must be enforced because it may ne argued that it is unfair that there is inequality of outcomes.
So it is clear that there are political forces tbat use thw easiest pressure points in the human condition to achieve low hanging political fruits. The fwelings of unfairness become especially inflamed during harsher times, so an economic downturn can be easily used to pass various socialist, even Marxist agenda, which changes the power balance in the ruling elite (those near the reigns of political power). This is done at the expense of economic health, any amount of political power over economic forces misallocates scarce resources and decreases economic activity in the long run, while achieving short term pplitical goals.
On a personal level, I woildn't allow unions to take over my enterprise, I would rather see the business shrink and restructure than lose control over how it is governed.
