The United States already does what I'm proposing, it's just a question of implementation. For example, the minimum wage dictates that if your business is only profitable when you pay employees $5 an hour your business doesn't exist. Capitalism in the US isn't so unfettered that only the market determines whether businesses exist. Some countries have stricter regulations around employee treatment (France started mandating paid vacation in the 1930s) and some have less strict (Singapore doesn't have a minimum wage), but this isn't some new idea.
