We just don't need as many person-hours as we used to need. The trend is only going to continue. Except in the case of people with exceptional cognitive endowments (like most of the HN readership), there's a labor glut.
We could just wait. The trend will continue. Eventually, things will come to a head (or several, under a guillotine). Instead, let's gracefully adapt to increased productivity by increasing the cost of labor. That's how we can let the population as a whole benefit from this productivity miracle.

I think one of the expected outcomes of ACA was that people who could afford to retire, but were too constrained to buy their own health insurance, would leave the workforce.
