I do think there is merit to reducing yearly hours worked in the USA. The problem is this is all within a larger system. The USA’s broken health care system makes it extremely expensive to hire workers. One way to deal with the health care system failure is maximizing hours worked to spread out the massively expensive USA health care costs.
Also the USA standard of living is partially based on long hours (it is but one factor). We also have to work quite a few hours (about 5% of the total hours) to just bring us equal with other rich countries, in order to pay for our broken health care system.
Still reducing our purchases by cutting out some fancy coffee, a few pairs or shoes, a few cable channels (or all of them), text messages from overcharging phone companies… in order to have a couple more weeks of vacation would be a great tradeoff in my opinion. And one I have made with my career.
I have changed to part time in 2 of my full time jobs (to make my own sensible yearly hour model even if the bigger system can’t. Another time I bargained for more vacation time over more $. It isn’t easy to do though, most organizations are not willing to think and accommodate employees (hard to believe they respect people in this case, right?). The system is not setup to allow people to adjust total hours to maximize their well being.
Another option in the USA is to live within your means and then make your own sabbaticals during your career. Take a year off and travel the world, or hike the Appalachian Trail, or read trashy novels, or whatever you want.
