You mean without kids, not owning place you live in, likely sharing flat, without abroad winter/summer holidays, living in places with good public transport without a car, where employer can actually accept 2 days a week employments?

no, you cannot. Not everyone can. At least, not in Germany. People pay 60% of their net income to rent while working 40 hours a week. How do you expect the rent to be paid with just 15 hours of work per week in Germany?

The big con is working 40 hours a week to afford to rent/own/buy a place to live so you can continue working said 40 hours a week.

Cut it to 15, move to cheaper residence and cut out gadgets, buying useless shit and owning lots of things. This frees up huge chunks of time and creativity and freedom. The freedom you thought you were working towards toiling 40 hours of your life per week.

yeah, see what happens to the economy if half of the people take this way. Let me call bs on that.

You mean the economy which produces all of the useless things that the parent just said we should stop consuming mindlessly? Slowing economic development is a benefit.

Ok, I just arrived to Europe. What do I do next?
