But cost of medicine, education, housing - all those essential things relatively to the income - all that is worse than 50 years ago.
Yes; I would agree; and while doing so I would point out that 50 years ago a friend of mine would be dead 4 years past, but a new and different drug for treating cancer has kept him alive and in the workforce for the last 4 years. It is basically now past the testing stage (he was in the last round of testing) and at a cost of somewhere around $45,000 a treatment, once per week, he is graced that he has a solid medical insurance policy and that he is not charged; as the treatment has still been in testing. But getting from the few dosages currently made (because it is in testing) and determining if it will be a world- wide available drug (which brings down cost because of greater availability) it is still going to be expensive.
And 50 years ago it had not even been dreamed of, as the science was not yet that developed.
Housing 50 years ago had far less selection; houses were pretty much cookie cutter and that vast majority were not the 2500 to 3500 sf “light white bright” boxes that the now de rigueur $100,000 to $200,000 family of two working parents, 1.9 average children and a designer do now want.
the population also has grown, and more houses have been built, which equates with more ground having been developed and less ground available for development, and the rule of supply and demand is not going to be rewritten because we now have Marxist children in the streets demanding it.
Housing costs are considered astronomical and depending on the area, they are; other areas are far lower.
A friend bought a house in late 1979, tract house in a 200+/- housing development; 3 br. 2 bath 1420 sf; it was the second form the bottom in size at the time. In 2015, after a complete remodel including new windows, new doors, complete renovation of the bathroom and kitchen with new cabinets, new appliances, granite counters, and a mix of hardwood and carpeting flooring, a rebuilt three tier deck of about 600 sf, and complete renewed landscaping for $329,000. At the time, no other house in the enighborhood had been so remodeled, and it was the equivalent of a brand new house. Except that no builder was building one level houses in that size anywhere in the area.
Had it not been remodeled, it would have sold for $60,000 to $70,000 less - and needed a remodel. That would equal an average appreciation of about 3.85%. a bit high of the usual rule of thumb, except that the area was fairly well built out and close to the main city, and an urban growth boundary was forcing land prices higher still.
That owner had to stretch for all they could when they bought. Just as young people have to do now; except many of them neither have the financial discipline or knowledge to do so, nor are they interested in what their parents or grandparents had to sacrifice to give them what they now have - including opportunities.
