> Anyways, my point is that tons of people who are not at the top of the businesses experiencing increased productivity are reaping the rewards of productivity improvements. It's a falsehood to think that only those making the investments are reaping the benefits. It only looks that way if you myopically don't look beyond the firm whose productivity improved.
Your point literally misses the point. From the perspective of improving the lot of ordinary workers, "beyond the firm whose productivity improved" doesn't matter. What matters is peoples' paychecks.
Before the mid 70's, when overall productivity went up, wages went up. That is no longer the case. It wouldn't be a problem if things like housing (both home prices and rents), education, medical insurance, and healthcare services (which is still important even for those with health insurance due to out of pocket maximums and deductibles). Notice how all of these are basic essentials of life, some of which are essential enough to form the base of Maslow's hierarchy of needs? I also want to stress that people today have to fund their own retirement, because there are no more company pensions.
Things that have gone up at or below the rate of inflation since the mid 70s are, by and large, not essentials: cars, computers, airline tickets, phone service, TVs, and clothes. [0] Granted, clothes, and sometimes cars are essential, but the savings there don't come close to making up the shortfall in the other things.
> Also, not all productivity improvements are from tools that still need to be used by workers. A lot is from automation.
If anything, I would guess that automation has harmed workers by eliminating good jobs, rather than benefiting people overall. Yeah, we have free stock trades now, but who cares?
I'm open to being convinced otherwise on the automation point, but I have a hard time seeing how people like my mom and dad, neither of whom went to college, could make it into the middle class today if you waved a magic wand and made them 25 again.
