Oh look, you're in kindergarten

I do ACA and Medicare everyday spanky, there iss nothing you can teach me.
Wrong. The government sets the rates for Medicare enrollees , not private insurance
Nope, rates are filed in the state the company is doing business in.
You can go to any participating doctor in the united states
Only with the Medicare Supplements, not the other plans.
Under Medicare, you can go to Johns Hopkins, Mass General or UCLA med to get the best care available, all self referral.
Nope. ONLY with Medicare Supplemental plans, not the other coverages.
ACA is not Medicare.
Never said it was. The ACA is Bammy's baby.
As for the ACA plans rate increases are either approved at the State level (9.9%) or less, or HHS (10% or more). The ACA also stipulates that 80 cents of every Prem dollar collected must be spent on claims. That leaves 20 cents on the dollar to pay ALL of the administrative costs. Pretty skinny margin there pop.
