If you're saying everyone is providing your point, I think you disproved your own point.

They're doing it because we are conditioned to want it.

Conditioning a behavior is basic psych101. It's a controlled external stimulus which illicits a desirable action from the subject. So a conditioned consumer is subject to external stimulie which illicits them to spend. I wouldn't blame the subject here, I'd blame the one doing the conditioning.

Regardless of all that, you are right but so wrong. We are all to blame, but I mean corporations and us. Politicians and the oligarchs aren't responsible for what you or I do. What they are responsible for is manipulating systems to benefit themselves over the interests of the general public.

Since politicians and the business elite wield so much influence that makes them more responsible than you or I who really can't make a big difference on our own. You're blaming the proletariat for being the proletariat, but we don't choose whether or not we are. You can work as hard as you can your entire life and you'll never amount to the level of power and influence Elon, Jeff, Mark, Bill, or Steve had/have.
