This is paving the way for the fascists to take everything over a certain amount. “You already have enough money.”
This crew thinks far larger than that. All they have to do is immediately yank QE and the markets crash (which many 401k's are vested in) and they can strong arm the American populace into going along with myRA ("my" in this instance means "theirs"). Little tinfoil, I know, but I never thought the SCOTUS would find the ACA "legal" (and actually HELP make it legal).
