It's not just that Obamacare is financially unsustainable. More seriously, it is intellectually unsustainable, even though this truth has been slow to emerge. This has come to an end with President Trump's executive order.
What does it do? It cuts subsidies to failing providers, yes. It also redefines the meaning of "short term" policies from one year to 90 days. But more importantly–and this is what has the pundit class in total meltdown–it liberalizes the rules for providers to serve health-coverage consumers.
In the words of USA Today: the executive order permits a greater range of choice "by allowing more consumers to buy health insurance through association health plans across state lines."
The key word here is "allowing" – not forcing, not compelling, not coercing. Allowing.
Why would this be a problem? Because allowing choice defeats the core feature of Obamacare, which is about forcing risk pools to exist that the market would otherwise never have chosen. If you were to summarize the change in a phrase it is this: it allows more freedom.
