However, I can't truly pick when I want to work. There are no jobs in my area that pay 80% of my current rate for the same task done 4 days a week.
If a job was truly an even exchange of value between employer and employee, I would expect to see some people working 7 days a week and making 40% more than me, and some people working 3 day weeks and making 40% less. But aside from service workers with work on nights, weekends, and holidays, everyone in my city went to work in the dark this morning and will go home in the dark tonight.
I am not against trading labor for money - that's the point of a job. I am against trading freedom plus labor for money.
