You may be missing the implied point of some of the comments. It sounds like you can make this work for you and you aren't barely scraping by renting a place where if you lose one of these jobs worry about taking a crippling pay-day loan and then what? Some people really do live like this today.
There is a fear that future generations will be by and large unable to have a choice. They have to compete for a first job out of college for possibly meagre hours with more experienced people that don't yet want to retire, against other people in the same situation, and also large scale automation. With it more common to stay living with your parents and sharing with other people rents where in the past one income was enough to purchase a (modest) place, more commitment possibly being tacitly asked for at work over contract type employment with no security it doesn't look so rosy.
I figure a solution could be to move from a 7.5/8 hour day to a shorter day with the same pay and continue down this path to match the employment opportunities and pay. Automation alone could render most jobs not necessary and some (possibly most) of the jobs we have today don't really do anything for society other than pay people and keep them from mischief.
