I don't know what to tell you if you think that. I guess don't put in effort in a menial job? Just quit, slack off and post on HN instead?
I don't think menial work leads to "mortgaging your body". Some jobs sure, but those very physically demanding jobs pay well because the alternative would be a job that pays equally as poorly and is not physically demanding. You can always default to working at a grocer or fast food job.
Those factory jobs at Amazon that are fairly grueling pay a lot better than similar jobs in those areas w/ that skill set. People don't really work them very long either due to the demands. So you can do that for a few years, make more money and hopefully invest it in building out a more valuable skill-set or give better opportunities to your children.
