You’re absolutely right. However, if you use the right magic words you can convince them that it will be good for them. Constituents will be happy because their bills will be guaranteed to be paid by their company, and investors will be happy because they can look at a company and instantly see whether they can make money off it. It just so happens that politicians tend to be into the same things as investors
I realize my other comment didn’t actually properly answer your concern. You are right about this being the equivalent of minimum wage. However, the meaning of wages have changed since the time when those laws were made. We don’t need companies to prove they can pay their people for today, because we have technology that lasts hundreds of years if properly maintained. We need them to prove they are economically viable forever.
