Obviously the opinion of this righteous blogger is that we should have Medicare for all, or be incrementally lowering the eligibility age, but now it appears we're getting into the crazy season and the Very Serious People have decided that increasing the age is the appropriate punishment for the olds for being olds.
No one listens to me, but one thing people should consider is significant numbers of married couples have one spouse with decent employer-based insurance which covers them both. Also, significant numbers of married couples are separated by a few years, with the older spouse being the one with the employer-based insurance.
This is an issue already, of course, but if you increase the eligibility age it becomes even more of an issue. How does that 57 year old spouse of a 67 year old retiree get health insurance?
Yes the great and glorious era of Obamacare will (hopefully) improve the individual market for health insurance a bit. But it's still going to cost. A lot.
