The subsidies are a huge deal for Obamacare. That was the basis for his untruth that the average family will see their premiums decline 2500 a year. That drop in out of pocket premiums was supposed to come from the subsidies.
Realistically, lots of people will drop their policies if they don’t get a subsidy.
This will be interesting to see, as this goes forward, if millions of people get fined for not having health insurance, when they don’t have it because they can’t afford it without the promised subsidy.
The real significance of this decision is where there are no subsidies there are no taxes that can be collected for not having compliant insurance. This would allow states that don’t have exchanges to allow “sub-standard” policies that would allow coverage as before Obamacare.
