edit: oops, wasn’t talking to me but will leave the below unedited for posterity (and to show my posterior).
again, that’s a logical leap that i was careful not to make. small-time investing can have positive externalities on an economic system; industrial, mechanized investing, not so much. if we didn’t try to turn everything related to money into a get-rich-quick gambling scheme instead of the (imperfect) accounting mechanism it was originated to be, we’d be much better off, pensions and 401(k)’s included.
Edit: sorry that was a bit snarky. The point is that there are other ways to ensure people have a reasonable lifestyle once their 'working days' are over. Those schemes are probably best to be tied in some way to contributions, but they certainly don't need to be simply a savings plan, they can be a means to provide social support for those that cannot contribute to the same degree as others.
