I am not from the US but I always interept it as, “Fellow American, I see these politicians are putting policies in place that are making your life hard, they don’t affect me as I’ve put things in place to avoid what happened to you from happening to me so I will support these people who continue to do things to affect groups of people as I’ve done well enough for myself thus far”.

Until of course the same politicians do something that affects them personally and then their tune changes to, “Why would they do this to me? I’ve always supported them!”
