i can't wait for the "there's been confusion about what we've done" message to come out. cuz its always us, right? the customer is always wrong in this era of techno-feudalism.
Or, antitrust laws that can break them into smaller units, recognizing that strict monopoly is not the only market failure scenario. That would be good too.
I think that is just called "government".
It's true that government is vulnerable to capture, but from that it does not follow that government is bad. It is more logical to conclude that the problem is unbounded personal enrichment allowing individuals to catapult themselves above the law. Corporations are the Roman Legions of the 21st century.
Corporations are also vulnerable to capture, after all, and that is their default condition. Why should we not treat powerful conglomerate corporations with the same skepticism as governments, or armies? Their internal structure is an inefficient command economy, why is this not also treated as a problem? Their scale, diversification, and entrenchment, have all allowed them to escape the regulatory power of market competition.
The problem isn't the wealth. The problem is the power.
The correlation between wealth and power is even stronger in countries where government is weak, and it is thus the function of government to prevent wealth from obtaining unchecked power. It is no wonder that wealth would seek to destroy government. That we appear to be losing this fight does not invalidate its importance.
You may have your choice of oligarchs to buy your car from, but what they will never allow you is the choice to compete with them on a level playing field. A cartel can allow internal competition, but they will all cooperate to crush upstarts.
It's government that interferes with competition, not "oligarchs" or "cartels." Otherwise I could buy a Chinese EV. The only way the "oligarchs" and the "cartels" can interfere with my decision is by using their wealth to capture and subvert the government.
Again: the problem is the power.
