The changes already made are already making a big difference in some places.
I live in a place where for donkeys years it was a rite of passage for teens to have their first jobs at a tourist attraction. They worked weekends and holidays, some did after school.
Now the bulk of those jobs are taken by people who have retired from their career jobs, but can't afford to retire fully. Same with a lot of Saturday jobs. Even the local paper is delivered by an older chap.
I think it's having a major impact on the maturity of the young people - everyone takes that step of maturity when they get their first job and it's just not happening at the same ages as previously.
