To start, “rich people using the government to benefit themselves” has defined the American political system for more than a century. As Murray Rothbard laid out in great detail in his book The Progressive Era, the transition from the laissez-faire, hyper-limited government system of the mid-1800s was not driven by the bottom-up plea to protect workers and keep food clean that we were taught about in elementary school. It grew out of the recognition among the heads of industry that they could much more effectively protect their market share from smaller competitors and go on to expand it if they used the power of government for their own benefit. In other words, the key to staying on top switched from innovating to lobbying.
That started with railroad companies in the late 1800s but quickly grew to include industrial farmers, healthcare providers, and bankers in the early 1900s, followed by weapons companies, Wall Street firms, and many others in the second half of the century.
Today, virtually all the giant corporations that dominate these industries owe their positions to government policies set up in their favor—to the detriment of the American public.
The modern political establishment is defined by their willingness and ability to protect and expand this dynamic. It is laughable to hear them falsely criticize Musk for doing the same thing.
