Nonsense.
Most of the people in the Obamacare Medicaid expansion are the working poor.
The real goal is to move people from Medicaid to a for-profit Obamacare plan where the skim rate (and the taxpayer-subsidized tax credit) is much higher. As an added bonus. the low-income person now has a crap for-profit plan with higher deductibles and co-pays, making it harder to see a doctor.
Moving a poor person from Medicaid to a for-profit plan costs the Gov’t more because of the size of the Obamacare tax subsidy to the insurer.
