I think not everyone who is making these sorts of comments is actually born into the privileged classes in that sense, but I know a lot of folk who have simply through luck never been out of work or seriously ill, who assume that they will continue to be that way forever. (I have a partner who takes this attitude, not about taxes, but about debt) - These are the people who REALLY make me headdesk. They're at risk, but don't understand, or want to know it.
