Boomers got pensions, then killed them off and barely paid anything into social security while sucking it dry. They get to double/triple dip into retirement with pensions, SS and 401k as a cherry on top. Younger gens basically fund that while the SS collection age keeps getting higher. So we are saddled with 401ks because that means our future is tied to the market creating a financial incentive not to push back to hard on the system.
