True, but its capabilities have grown since then, too. Things like monoclonal antibodies can now cure very serious conditions, but they are very expensive to produce.
In the 1960s, cancer was an almost certain death sentence, nowadays, it is often manageable - but that increase in survival comes with a price tag.
Since 1970, the poverty rate among seniors has dropped from almost 25% to just above 10%: https://sgp.fas.org/crs/misc/R45791.pdf. Although more people had pension plans (though never a majority), they were not portable, and most workers never stayed at a job long enough to earn their pension. Pension benefits were also low compared to what they are now. See: https://retirementlc.com/golden-age-pensions-another-fairy-t...
Healthcare was cheaper in 1970, but because doctors could not do much for you if you got heart disease or cancer or other chronic illnesses. In 1970, 40% of heart attack patients who were hospitalized died. Today, it is well under 10%. Living longer doesn’t happen automatically, it costs money. Not just to develop heart medication or cardiac stents, but for the decades of additional care that is required when a heart attack patient survives to old age instead of dying at age 55. It’s not just old people either. The infant mortality rate has dropped from 26 per 1,000 in 1960 to under 6 per 1,000 in 2020. That wasn’t from cheap interventions like vaccination, which happened a generation before that. It was from expensive interventions like giving birth in hospitals, extensive pre-natal care, surgical interventions for sick infants, etc.
The costs per square foot of new houses has stayed pretty much the same from 1970 to 2015: https://fee.org/articles/new-homes-today-have-twice-the-squa.... What people overlook is that (1) as the population grows, the "frontier" of where the typical new house is being sold moves; and (2) people are using their growing income to buy much bigger houses. For example, Silicon Valley was an underpopulated, undesirable suburban and rural area in the 1960s—that’s why they built semiconductor facilities there!
It’s important to account for both price increases (paying more for the same thing) and consumption increases (paying more to get more). A good example of both of those things happening is college. The cost of college has undoubtedly gone up faster than inflation. But it’s also a very different product than it was in 1970, with fancy housing and recreational facilities and tons of handholding from support staff.
By contrast, housing is a good example of something where it’s been mainly consumption increases. People are taking all their extra income and using it to buy bigger houses in more desirable areas.
So in other words, "inflation adjusted" wasn't done right here?

That's a type of inflation. The share of cost burdened renters has increased by 1.3% per year relentlessly for 55 years.
