Those enrollment projections are for the marketplace - not Medicaid which has far exceeded projections (this is gonna be a problem for the states which chose to expand Medicaid through ACA). Please don't knock the messenger - I'm all for reducing the debt and all this spending. I don't see Bernie or Hillary's policies reducing but expanding the debt.
My solution is to stop all this influx of immigrants into the country who are further staining our educational, social, welfare systems - integrate all those who are here (probably takes a couple of decades), slowly raise the age for SS to 70 and keep raising accordingly as life expectancy rises, match Medicare age to SS age (this is in the GOP's plan), offer an amnesty period at low tax rate for corporations to bring back the trillions parked abroad with the understanding that it'll be spent on creating jobs, lower the tax rate for corporations so that it's lower than Canada/Ireland/wherever the companies are running to, no more H1-B visas - hire or retrain American workers, try to renegotiate NAFTA, stop TPP (see Trump's speech today), send education back to the states (which hopefully will try school choice so that kids aren't stuck in bad schools), loosen the rules and regulations on businesses (there are now more small business closing than starting), repeal and replace ACA with the GOP plan and keep refining it.
What are your solutions?
