The more modern interpretation has basically been "monopolies are ok if it lowers consumer prices", which sort of never made sense. Once you finish strangling all your competition, wouldn't you then raise prices? And then what, the government lets them do that until some vague line in the sand is crossed and we then actually enforce the law?

There are issues on the other side too - monopsony, where a company is so big they are the only nature buyer. You get this with Walmart being able to disproportionately squeeze their suppliers. You have this problem in labor markets sometimes because who else are you going to work for if your employer is super sized?

Lina Khan's writings, and the fact that Biden admin appointed her, indicates these recent assumptions about allowance of monopolies can probably be thrown out the window.
