>I don't want to spend most of my life working. I feel like a slave, and now my youth is almost gone.

That's a first-world problem if I ever saw one.

You're going to work most of your life because if you don't somebody else will have to support you. Very few people can provide for their lifestyle without working (it can be done, but it can be very hard and would require a sacrifice of some of the comforts of modern-day).

And yes, you can do 4-day work-weeks. Become a contractor and then you can set your own hours and your own schedule though you'll have to find your customers.

>Weekends offer barely enough time to catch up with chores. There isn't enough time both to catch up and still have fun. I use vacation time to catch up on chores, so that's spent too

Please don't tell me you're single because if you're single or in a relationship without children, you can easily get caught up on your 'chores'.
