Eventually, all co-pays will be zero.
We see it now with birth control and a lot of Medicare patient medications. Once we're all on government assistance with the New World Order, all co-pays will be reduced to zero. Reimbursements from the government will fall below the cost to fill the medication as mandated by law. Pharmacies will fail to make a profit. Many will close. The remaining ones will be taken over by the government... one by one, until all pharmacies are government-run.
There will be no more brand medication and no incentive to create new drugs because there will be no profit. Without profit, no one will invest in drug development. The only drugs available will be shoddy generics, and the government will only allow the purchase of the cheapest of the cheap in their newly owned pharmacies.
Getting medications filled within minutes, or even the same day, will be a relic of the past. Without any incentive to work, your pharmacist and technicians will move just slightly faster than your local worker at the post office or DMV. We'll all have that same expression on our face... dull, tired, and worn out.
Without new drugs... and consequently new antibiotics, bacteria will mutate... and will get stronger and tougher to kill. More people will die because there will be no incentive to create better drugs.
Eventually, we'll all die from a Super Bug, all because YOU demanded a zero co-pay.
