I do, as do most people. When you hear talk about subsistence farmers who live on less than a dollar a day and don't have running water, that's what the "few acres of land to be self sufficient on" lifestyle looks like in the absence of a strong market economy.

Have you looked at the homeless in your city? Sure they might be fed with cheap food, but they are living under bridges. So, that is what a "strong market economy" gets you too.

So don't compare the worse case subsistence farmer, with what was middle class in the US a few decades ago, where suburban houses on a couple acres were affordable my the top 70% of the population. We have more trinkets, but the price of basic necessities are becoming more "expensive" every day.

These are the average case subsistence farmers. The worst case ones live even harder lives than an homeless person, very often dying of starvation after a bad harvest.

The middle class in the US a few decades ago lived pretty good lives, but were very much dependent on market economies and innovation for their standard of living.

You can easily have "a few acres of land to be self-sufficent on". Clearly you don't value that, so you don't have it. If you actually value it, go get it.
