The way they do that is with an induced form of "disaster capitalism," where they intentionally crash the economy in order to have some control over what remains. So the function of tariffs, for example, is to bankrupt businesses or even public services in order to privatize and then control them. Stall imports, put the ports out of business, and then let a sovereign wealth fund purchase the ports.
I've got a genius business idea for people with few discernible skills. First you establish a health insurance company and get people to pay you large sums every month. Then, when a customer tries to use their insurance to cover medical costs, make a habit of denying their claim. While doing that, pay lobbyists to keep politicians amenable. Repeat this strategy until your company is worth billions. I'm not saying this is exactly how the US health insurance industry works, but it's close enough.
Take the old example of Ross Perot: Before he was a presidential candidate, he made his fortune producing welfare forms for the federal government. Today, this dynamic has evolved into sophisticated disaster capitalism, where public benefit systems create ideal conditions for private equity extraction that devastate both vulnerable communities and nonprofits.
