I don't think it is possible most of the time, they're a lost cause. Individualism in the west is not just a personality trait but extremely tied to cultural behaviour and identity, rejecting individualism is often seen as attacking western/American values of freedom and autonomy.

Maybe it is possible in the rare cases this person happens to be a hypocrite and they happen to have benefitted from some form of government program or maybe they have some personal aspiration that could be fulfilled through some government plan but they don't realize it due to misinformation.

I think a simple example was the Bernie campaign for healthcare and meeting people that still believed their insurance costs would be higher or their service quality would be worst somehow. At the very least you have to make sure they don't have these false beliefs as part of the foundation.

But as I said imo American individualism is so tied to culture that nothing short of massive government re-education through a revolution would change anything. It is a lost cause really. The most you can hope for is these people are not the majority because eventualy they'll become hypocrites themselves, material conditions etc eventually everyone will desire something and if that can be provided by society then it can be the start.
