So if you want a better standard of living than Caesar or Charlemagne or Washington could have dreamed of, you have to work, yes. Is that shocking or unreasonable? I doubt the men I just named would have thought so.
Lets just talk food - the work required to produce enough food to feed 1 person is astronomical and completely inefficient if everyone did it for themselves. In order to reach some efficiency (i mean, you aren't gonna just eat raw wheat right?!), there must be specialisation. Which means that if you were to really live alone, you'd have to aquire all the skills and all the equipment in order to produce food.
You can substitute food for anything else, and the story is the same.
The world as it is now, is pretty m uch the result of specialization over the millenia, your job (if you have one, or your business) is in fact some form of specialization, and it is this specialization that allows each and every one to eat, because they contributed back something they specalized in.
I'm a dual Polish/US citizen. Poland has better life expectancy according to the CIA Factbook than the US does. Poland had an average income of 240usd per year as recently as 1989. It's about $20k today. Still can provide better life expectancy than the US. Shame.
I'm a Swedish/Australian dual-citizen, and although both countries have higher costs of goods, it seems a most reasonable price to pay to have functioning public health care.
What I meant by "subsistence living" is working enough to cover the essentials, and no more. These essentials include food, water, shelter, and healthcare.
The problem is the last one: it is astronomically expensive, which means that subsistence living still means working a ridiculous amount of hours.
