Nothing destroys class consciousness more than 401ks in my opinion.

• The working class is divided into people who get 401ks because they have arbitrarily defined "good" jobs and people who don't.
• Social security is de-emphasized since 401ks are "better" and poors can go fuck themselves I guess.
• As far as your 401k is concerned, your interests are completely aligned with the bourgeoisie. You want wages to stagnate (for everyone but yourself?). You want big profits. You want a desperate working class. You want low inflation austere fiscal policy.
• With everyone buying into these funds, it is literally pushing up prices of assets rich people own.
• Rich people can use their inflated assets as collateral to borrow money at lower interest rates than the rest of us.
• Buying stock in a thing has either no link or an extraordinarily weak link to actual money being invested in the thing, so you're not really even creating employment opportunities for anyone. I think socially conscious investing probably achieves little to nothing. Money just bounces around like hot potato until it ends up funding a deep sea oil rig or something.

But there's no alternative. Your individual actions won't change anything and you understand that you're literally going to be invested in you and your fellow worker being poor and the alternative is making sure you can only live paycheck to paycheck.
