The argument goes that these low-income individuals above 300% of the federal poverty guideline (FPG) represents crowd-out which is bad for the insurance business. These people could theoretically afford to buy their own private insurance rather than Medicare.
I agree this is a bad thing, but I don't hear the industry complaining about it. Just these anti-socialist paper-tiger builders. This is just old-fashioned cherry-picking. The lower the income, the poorer the health, the less desirable to insurance companies. If the insurance companies off-load these patients to the public rolls, they're all happy.
But I thought we didn't have that many uninsured vulnerable people in the country anyway since the Census folks got it all wrong , so I guess it doesn't really matter. It won't cost anything to extend insurance to non-existent people.
