Antitrust needs to make a comeback in general. I've been seeing meme-graphics about consolidation in various industries (like how most of the stuff on the shelves in grocery stores comes from like a half-dozen companies, even if there are 20 "brands" on the shelf making the market look healthier than it is, 18 of those 20 will actually be owned by those very-few companies; ditto media, telecom, et c.) my entire life.

Why did everything consolidate terribly in the '80s and '90s? Because we basically stopped enforcing antitrust in the '70s, due to Chicago School jackasses influencing policy and jurisprudence.

We need to undo their fake-pro-markets horse-shit and get back to having robust markets in every sector, not just software (but yes, certainly in software too). That'll require a spree of breaking up big companies across the economy.
