Yes, the consumer economy harms people in order to sell them things. Advertising only exists to make you feel like sh-t so you'll expend the wages of your substantial work for their worthless garbage. This is true for any group of people you can imagine. Consumerism is fundamentally anti-human and we have lived under its brainwashing now for close to 100 years. We are bombarded with propaganda 1000x times as lethal and dehumanizing as the worst police state, in the service of commerce. Unless we reject it we will just be the customer serfs this system is designed to produce.
But the Homeric Greeks were very, very different. They don't fit that pattern, except by analogy. They sucked, of course, because all societies suck, because all societies are the imposition of the bigotries and fears and vanities of the numerous dumb at the expense of the few smart. But they sucked in a very different way than we do. In a millennium the next culture will suck differently than both of us.
