So you're going to be rebelling against "an economic system characterized by private or corporate ownership of capital goods, by investments that are determined by private decision, and by prices, production, and the distribution of goods that are determined mainly by competition in a free market"?

Words have well-established meanings -- precise definitions, even.

Will you be embracing socialism or communism instead?

I think what you mean is that you intend to rebel against *unrestricted* capitalism in what has become a far cry from an actual free market.

There's nothing whatsoever in capitalism itself that requires or even necessarily leads to "mindless consumerism and more-wants-more-attitudes, against insignificant products that get ugly and/or fall to pieces after just a short phase of usage and that cannot be repaired, and against each-to-their-own-mindsets and unwillingness to share", all of which I object to as well.

Let's just not throw the baby out with the bathwater.
