Fannie Mae-No Politics (FNMA)

[TheDon3]

"As part of the Affordable Care Act, tax credits are available to help offset the costs of the premiums. Roughly 85% of Obamacare customers currently qualify for tax credits and the average subsidy in 2016 was $290/month. As premiums increase, so do the subsidies from the government. The administration has noted that nearly three-fourths of consumers can find plans for less than $100 a month with federal subsidies."

Can someone on here please tell me, how do they increase the subsidies without anyone knowing? Cause I know that can't happen through congress or taxpayers..if they keep increasing as the premiums do.it makes too much sense. It's related to the changes they made to the SPSPA in 2012!!
