I don't think that is true for older workers living today, but it was true on the 50s. The GDP per capita went up by more than 4x and yet it is those 50s people who have had an easy time owning a home.
Call it what you want. I see it all the time. And not many new slacker type jobs are being made, for young people to do the same. Every generation probably has the same percentage of people who don't do anything. The difference is that such a person who is young is a "neet" on unemployment, while such a person who is old collects a nice paycheck from a job.
