The dollar was worth more, but people made way less of them. Cars were less expensive, however, far less reliable and would not make it to 250,000 miles which is easily doable for a modern car. As others have pointed out housing costs have increased, but so has the size. You can still find plenty of affordable housing if you are willing to live in 1200 square feet. I'll repeat what I said on my previous comment. Life is only harder in the modern era for stupid people.
Unfortunately, there are far more stupid young people today.
