I love the other comments you made, but I want to point out one other thing: How did those privileges come about? That is, what were the conditions that led to the government taking the power to grant companies de facto monopolies?
In some cases, it was an unintended consequence of political conditions. For example, private insurers came to rule our healthcare system because of a cap on income to raise funds for WW2. In order to get around this cap, employers offered non-cash benefits and the rest is history. Libertarians love this one, it’s pretty cut and dry that a form of socialism shot itself in the foot.
However, there are many other cases where it was an unintended consequence of regulation written in blood. An easy and popular example is the FDA. Making food and adhering to food regulations at scale is definitely something that requires so much up front capital that it has been favoring existing corporations for quite a while, leading to a relatively small number of companies controlling a huge portion of the food supply. But that regulation came about because companies large and small, unfettered and unrestricted, were adulterating the food or cutting dangerous corners to maximize profit. The solution can’t just be less regulation, those same companies will continue to dominate but now with the ability to outright feed us poison while buying or otherwise destroying any competition.
That’s the neat part: Convicted felons ARE excluded from most public service jobs like being a teacher or a mayor. It was widely believed that this included the presidency until the Supreme Court decided it somehow didn’t.
