President Trump did this, by a stroke of a pen and repealing the Cost Sharing Reduction subsidies for the poorest on the exchange....in order to give the the very poorest on the exchange the affordable silver plan which is Mandatory for them to do by law, but without the gvt CSR subsidy, the Insurance companies had to raise their premium rates for all others on the exchange...and get their money from the government through the subsidies of all the other people buying on the exchange are given...
these raised rates do NOT raise the prices for the people getting subsides on the exchange...they all still pay the same amount of money according to what they can afford...and the govt is picking up all of the rest, they are paying for the huge increase and as said, not the customers....
so the insurance companies are getting the money for the Cost Sharing Reduction subsidy that Trump so FOOLISHLY repealed via the pen, by raising the price of premiums by 30% to 40% on premiums, of which the government has to pay....
the government, saved nil by Trump's reneging the gvt subsidy for CSR plans for the poorest, because they are now paying for higher subsidy assistance for premium for everyone on the exchange.
YES, Trump;s sabotage not only cost us tax payers more money, but also added huge insecurity to the Insurance market.
