What happened to pensions?
They were built on the concept of infinite growth. Eventually it became apparent that's not possible. It was also built on the idea of lifelong employment at one company or government entity, something that is between undesirable and impossible for many today.
How much was the cost of college tuition in the 1960s?
Welcome to supply and demand. By creating a loan program where you could borrow whatever you wanted and unlike most other loans could not absolve it through bankruptcy, you have an endless supply of loan money creating a false demand for "education." There is a fair bit of research showing a significant percentage of kids don't know more useful stuff and haven't refined their reasoning capabilities after completing college "successfully."
Starting in first grade in elementary school we had to pay attention throughout 50 minute classes. Try giving a 10 minute presentation at Cisco. People are twitching and spazzing, playing with their portables and otherwise doing anything to avoid actually paying attention to the presentation, and it's not just the new kids.
Or the cost of housing?
Again, supply and demand. In 1950 we only had just over 150M people in the US, and now we're close to 350M, and they all want to live near cities with the finest food, entertainment, education, high paying jobs, etc... but the amount of real estate in within a fixed distance of a city has remained constant. Indeed, the needs for ever expanding infrastructure has consumed land that was previously used for housing.
The 1960s was before the outsourcing of American manufacturing jobs, the creation of the H1b visa, and the "gig economy".
Yes, back when every electronic device was made from mostly standardized parts and came with a schematic. Even with that we had a live in GE repairman working on our black and green TV until the warranty was up, and it never did display either blue or red. In the early 1980s we imposed restrictions on Japanese auto imports and rather than improving competitiveness the US companies simply raised the prices on the garbage no one wanted and people still bought the Japanese products. Heck, even our best fish is exported while we import fish grown in toxic waste. On average Americans don't care about producing or consuming quality.
Also don't forget the cost of healthcare has skyrocketed.
Yes, we have by far the most expensive health care system in the world and one of the least effective for a wealthy country. Half the people believe that we should get rid of insurance altogether and just have the people in New York city trade the chickens they've been growing in their studio apartments to pay for health care. They also reject the idea that the government should use its negotiating power to reign in pricing. I'm waiting 9-14 months for simple appointments so the one complaint about foreign systems doesn't stand. Even when I see someone it's often no longer a doctor.
Household income didn't keep up with inflation after the 1990s.
You're late by two decades. Ironically the monkeys who voted to transfer all the wealth they create to people like me bought into the idea that if they get rid of the minimum wage and get $1/hr the investments they could then afford would bring them the Life of Riley. They worship people like me and call us "Job Creators" as their jobs are moved offshore. People are profoundly stupid, and the few of us with real investments who understand they aren't sustainable if you throw everyone out in the street are opposed most vigorously by those will be first out on the street.
Speaking of stupid, how many people who were saying here everyone would quit Cisco because Cisco had its first layoffs earlier this year actually quit?
