Well I would again say that such am argument simply wasn't being made.
I would also say that to the best of my knowledge the CBO did not break out how much of the decline in working hours would come from structural changes vs tax and income incentive changes.
If you would like to have a discussion about a different method of qualification, etc I would find that to be a very interesting discussion.
I would refer you to post 29 wherein I expressed my amusement at the exploding heads. In that post I quoted a CBO passage 3 times (in part and in whole) that spoke to the issue. CBO didn't quantify the effect if structural v incentive changes but they did say:
CBO estimates that the ACA will reduce the total number of hours worked, on net,
by about 1.5 percent to 2.0 percent during the period from 2017 to 2024, almost entirely because workers will choose to supply less laborgiven the new taxes and other incentives they will face and the financial benefits some will receive.
In context they are pretty clearly stating that the qualitative majority of change in labor supply is due to incentive changes and not structural changes.
I will state again that the Republican talking point of "OMG fewer jobs!" is misleading. I will also state again that the Democrat talking point of "Job mobility!" is also misleading.
If "job mobility" were a true driving factor we would not be seeing a reduction in hours worked. That I can leave my dead-end 40 hour/week job without fear of losing my insurance to get another 40 hour/week dead-end job results in no loss of work hours to the economy. That's one form of "job mobility." That I can leave my dead-end 40 hour/week job to start my own business without fear of losing my insurance should also result in little if any change to the economy, since I am still working. If anything it should increase the number of hours worked since I am still working 40 hours and my old 40 hour job will be filled. That's another form of "job mobility."
If "job mobility" were a true driving factor then the only ways changing jobs would result in a loss of hours to the economy are:
1. Employee moves from Job A to Job B at equivalent (40) hours. Job A is eliminated. Now the two jobs contribute 40 combined hours to the economy instead of 80;
2. Employee moves from Job A to Job B at reduced hours; or
3. Employee leaves Job A to start a business and Job A is eliminated.
Are there other general scenarios?
I think it's safe to surmise that the scenario outlined in the CBO report is none of these three things. Under scenario 1 we would have to accept that 2% of all current jobs are not needed. After all, why would an employer eliminate a needed position that became vacant. Are we willing to accept that coming off of record unemployment, when several states are still years away from recovering, that 1 in every 50 jobs (on net!) isn't needed? I can clearly not choose the wine in front of me. Scenario 2 only works if Job B was at equivalent hours to Job A prior to the hire. That would mean that Employer B would be part of the reduction in hours. Yet the CBO tells us that demand for labor will remain strong (even pulling some people back into the labor force) and any weakness in demand in certain sectors is likely to be reflected in wages and not job equivalents. I can clearly not choose the wine in front of you. Scenario 3 only works, again, if there is reduced demand which we know to not be the case. So I can clearly not choose the wine in front of me.
OH MY GOD WHAT'S THAT OVER THERE!?!? (*switches goblets*)
No, the unfortunate message in the CBO report is that the ACA will be the impetus for tens or hundreds of thousands of workers to decide it's not worth it any more. Why work 2000 hours a year, pay taxes, pay for health insurance, and not see your kids when you can maintain the same standard of living working 1500 or 1000 hours? If SNAP, TANF, WIC, CHIP, Medicaid, premium tax credits, and cost-sharing reductions can leave you with just as much money and twice the free time, why not? If I choose to work less then my employer isn't cutting jobs (which the CBO reports isn't happening). If I choose to work less or not at all then I don't increase employment or unemployment (which the CBO reports won't be increasing). If I'm affluent and my means aren't stretched the ACA doesn't give me the marginal incentive to not work (which the CBO reports is correct).
The CBO report says those at the tax/disincentive margins (low-income persons) will voluntarily reduce their employment and maintain their standard of living. How will that happen if not for expensive public assistance programs?
A nebulous concept like "universal healthcare" likely wouldn't have these disincentives. Is the care doled out in Canada or the UK income- or means-tested? A quick Google indicates 'no' but I could be wrong. Assuming I'm right, these systems wouldn't have the marginal disincentive to not work. (Under the ACA earning $1 more can push you out of a CSR tier, greatly increasing your deductible and OOP costs.) That's not to say that universal healthcare doesn't have its own disincentives (why work at all when you pay the same amount?).
