Well... and that's the problem. It sounds easy on paper but in fact it is not easy at all in practice for the wide masses:
- work 8 hours, add 1h overtime and lunch, add 2 hours for commute, so out of the 24 hours a day, you already lose 11 hours to work related matters. Add 8 hours for a decent sleep time and whoops, only 5 hours remaining in the day for everything else: getting ready for work in the morning (0.5h), do chores (1h), make, eat and digest dinner (1.5h) have some quality time with your partner (1h) and children (1h), and whoops the entire day is gone before even considering anything actually relaxing, hobbies, or working out.
- shift work, particularly rotating shifts, or on-call work that's effectively being abused as regular overtime, makes developing healthy sleep patterns outright impossible.
- many people are outright unable to afford healthy groceries, which is why they're going for unhealthy highly processed food
- of those that are able to afford groceries, good luck getting them in one of the way too many food deserts
Our health issues (and the lack of children) to a very large degree tie back right into the expectation that people have to work 40 hours a week just to afford bare survival. That is the true trap - systemic forces leave the wide masses no other way.
