Fundamentally, you’re never going to be able to compete with the economies of scale of an assembly line with the same people putting together all the parts that were shipped to the same place. If the repairman has to keep an inventory of hundreds of parts for dozens of models, and drive around to where he only has time to diagnose and fix 2 appliances per day, while the factory worker can install a part for 100 appliances per day, there will always be a gap between the price of replacement versus the price of repair.

Plenty of short-lived stuff back then, too. Survivorship bias means that all the stuff that happened to survive to today is not necessarily representative of the typical thing that was manufactured back then.

No, even if tuition and books are free, financial aid still needs to help full time students have food to eat and have a place to live and ordinary day to day expenses. In many places, the aid on room and board is much more money than aid on tuition and fees.

And community colleges tend not to have their own dorms or anything like that, so it comes in the form of a monthly payment that helps the student pay their rent. That’s an incentive for fraud.

Yeah, investing in a company is investing in the whole company and all of its projects. Lies about your company are only fraud when the lies rise to the level of making a material difference to how a typical investor would value that company. If the lies are about a very minor percentage of revenue or profit, then it’s not gonna rise to the level of securities fraud.
