Young people often hate capitalism, because idealism tends to see the possibilities of humans rather than our limitations. Marxism was very attractive to me when I was 20, then I grew up and realized (sadly) it's not realistic or practical or ever going to happen (see Cuba, USSR, etc.) the way Marx blueprinted or imagined it, or at all. I don't follow Greta but up till now her message, ADDRESS CLIMATE CHANGE, has been sound. We need to elect younger people in the US. The US could be leading but we worship consumerism as few other countries do. We export it. We need to push women's rights and birth control. The problem is too many humans but anti-capitalism can't fix that. I know it sounds cynical and awful....but our only hope is a plague that wipes out enough of us to give the planet a break.
