the underlying point is that money isn't the be-all-and-end-all of what we value and what we exchange in our socioeconomic lives. money collapses a multidimensional social calculus into a single-dimensional metric, with all the undesirable consequences of that kind of collapse. hoarding wealth is selfish, but it's worse when it also hoards power and esteem along with it.
not many wealthy people deserve respect (or power) along with their riches. people who make stuff with their hands and brains, not passively through wealth (e.g., rents), deserve esteem. that's the point.
More likely they hired workers who created that wealth. And while in today's system we say that the person at the top "earned" that wealth, we could just as easily arrange firms differently so they are cooperatively owned. And in doing so they would not produce super wealthy people but instead a society with broader wealth distribution.
More likely they hired workers and everyone created wealth together. A worker can't work until someone builds the assembly line, buys the materials, and sells the final product.
If it's so easy to do the whole process that anyone can do it, what's stopping you? Marxists claimed the capital class denied the funds to the working class to start their own companies. Well since the world went off the gold standard there is no lack of funding. It's the opposite now. Inflation is an attack on wealth. Wealthy people are ravenous to get their wealth out of currency and into "things" like property and businesses. Venture capitalists will fund the most ridiculous ideas in the desperate hope that one of them will "hit".
No, you have misunderstood. I am 100% for freedom of association and freedom of contract. "Consumerism" is not just exchange, it is something more specific. It is the idea that buying more is directly tied to happiness and well being. Look.
"Consumerism is the idea that increasing the consumption of goods and services purchased in the market is always a desirable goal and that a person's wellbeing and happiness depend fundamentally on obtaining consumer goods and material possessions.

Seems like you want to take freedom of association away from the rest of humanity and put it into your own hands. It's hard for me to imagine a mentality that is more self-centered and more selfish than that.
