But, the cause is not capitalism. There are many causes and all of them link back to regulation, government and an unwillingness to allow for lower cost options for (housing, transportation and medical insurance). For example in housing. Consider this: We could build the type of homes humans had 1000s of years ago very easily and it could be super cheap, only costing maybe a few dozen hours worth of wages to through up a couple of wooden walls and a ceiling but none of that is legally allowable. We've created an environment where only housing of the highest possible quality is legally allowable, thus forcing everyone to work long hours to afford all that whether they want it or not. this is further compounded by the fact that we're forcing people into a very tiny amount of land, thus driving up the cost of land needlessly when there's soo much empty space out there that can't be developed.
If given the choice, I think most beings would select into a stream optimizing for actual existence. Sounds strikingly close to evolution.
40 hours of work provides much more than subsistence, even at sub-minimum-wage income levels in the US.[0]
The vast majority of people earning an income in the US earn greater than the minimum wage. Only 2.1% of hourly workers earn at or below the minimum wage in 2018, and it's been trending downward for decades.[1]
Both a hunter-gatherer society and modern capitalist society offer opportunities for luxury[2] beyond subsistence. These are different. A value judgment between the two would be just that, and I don't want to fight about any differences among the things that you and I value.
EDIT : updated BLS link to latest, and reference to 2018, instead of 2017.
[0] Personal experience. I have lived at $10K/yr within the last decade in the US. My sister has, too. Note, this would be a full time $5/hr.

[2] See my comment sibling to yours for this non-standard use. I don't have a better word. Here, I mean "luxury" as "beyond subsistence".
There is a vast difference between hunting/gathering and what you think of when encountering the phrase "subsistence farming". You're on the right track when considering "the local strongman". Sedentary farmers of scheduled-harvest process-heavy plants (most grains) are vulnerable to the predations of government in a way that people who live more in tune with nature are not.
