Sure, under pain of starvation people will do this if gig work is the only possible work, but we try not to let people die in the west this way and as a result people have a little breathing room to try to choose better options. Even just being your own childcare is an activity with much higher returns in your example than 60 hours of gig work. I would not expect 50-60 hours to be the norm when it pays so little per hour.
