You are touching an interesting topic here: we produce more with less time and effort than before. This in theory should allow us more free time, but in reality we still work more regardless so that business owner earns more.
However, I see an issue here. The idea you defend does work when producing material goods, like food and goods where we need a means of production that is hard to acquire. But there are other methods where the means of production are cheap and available to everybody, like teaching, or programming or selling. I see here the biggest entry barrier is salesman skills like finding customers and clients, and ability to solve a multi million dollar issue. I chose that wording because raising a capitable in millions of dollars can be done in multiple ways most people do not comprehend. Personally, as a programmer, if I had the ability to convince people and find customers to build things for them, I would have my own company. Or if I had my salesman skills on point I would open my shop or commercial business. Those can also be considered means of production but since they are immaterial skills, I still haven't finishes building a slot in my mind to receive them.
The issue is when we see those skills applied they seem trivial or too easy anybody could do them but they are also so hard very few people does them. We also often think of them "what did you even do? I am here doing all the work producing all the product" which is true, but lacking customers to sell to is the problem a majority of my aquiances are struggling with.
I do not say those are impossible to do but where the means of production is a skill, how does it change or affect your take?
