It would not be a huge increase in cost, you would offer higher premiums for the older generations who could stomach it because they are wealthier.
Let's get real, the cost spikes in healthcare have NOT come from something that has been around forever like people in their 20's without insurance.
It has come from overregulation, advances in technology, ease of lawsuits and inability to buy cheaper insurance because the Patients Rights Act de facto forbids it.
I'm not speaking to you. You have no idea what you are talking about and just spout off a bunch of random, disjointed "facts" that have little to do with reality and even less to do with the subject at hand. Slow down, learn to read, learn to write and then maybe we can talk.
