I expect the issue will need to get addressed in the future, especially as the wave of millennials retiring will be far worse than the boomer wave.

I wouldn’t be surprised if it gets combined with a change in qualification age for Medicare. You push Social Security age qualifications up but push Medicare down to put the added healthcare costs on the Federal Government instead of the states. It would likely involve a slow ratchet up rather than an immediate jump. I can also see the deal include ditching the social security tax cap, or maybe adding a new tier.
