The point is - there still is (was) a choice. You can take the loan, or not. You can get creative and survive. Some won't. But some will. The business owner makes a conscious choice - this is the business I want to be in, they bust their ass, and they make it happen.
Choosing your career path is not so terribly different. For some people the path they desire is easy bc they already have the resources, no matter how expensive .gov allows it to become. Others find creative means to make it happen - via military service, via putting off to work and save up, marrying a sugar mama, whatever. Yet others have few options (say, you're a middle class white guy who isn't supported by the family, and don't qualify for selective service). Loans are about the only option.
Or... you suck it up and choose another profession that isn't your preferred.
Just like during the pandemic, a business could choose to change what they do. It sucks, nobody wants to do that, but it's an option. Everybody who got into the teleconferencing game and shifted their work to a virtual format sure as hell did well.
