Well, whether or not you get increased coverage depends on what coverage you have now. Since a higher percentage of young people are either not covered at all or have bare-bones catastrophic plans, young people in general are going to get a larger increase in coverage than old. The ACA plans, as I understand it, all give more coverage than current barebones catastrophic plans. So it makes sense that their premiums might go up.

I'm not clear on to what extent premium payments from the young are treated as being in same pool as the old, in the new Obamacare system. I do know that part of the problem leading to current situation has been that young people don't have health insurance or have barebones coverage and that older people have been to some extent subsidizing health care needs of the young. If the new system cures that then it makes sense that premiums for older people may go down; younger people will now be paying closer to their fair share.

Regarding premiums for the non-sick going up and premiums for the sick going down, not sure about that. But the whole purpose of insurance is to spread costs evenly. My understanding is that many insurance companies have until now been allowed to create high cost policies that are sold to sick people. This runs counter to the idea of insurance; the cost of insurance should be the same whether you are sick or not. You pay for the insurance as a healthy person knowing that if you become sick you will be covered. Having policies with cohorts composed entirely of sick people is antithetical to the idea of health insurance.
