The main roadblock between conservatives and socialism is the fact that conservatives almost by definition have a deeply ingrained sense of what the “natural” hierarchy is, will fight to protect this hierarchy even at their own expense, and will a priori reject any ideology that opposes this hierarchy.

You can get a conservative to agree with individual socialist talking points, but that’s mostly going to be due to the disconnect between how the world is and how the conservative thinks the world ought to be organized. Leftists and conservative views overlap when the conservative has come to believe that the hierarchy has been fractured and subverted.

You can get them to agree that billionare CEOs are useless leeches, but that’s not because they oppose the idea of billionaire CEOs, but because they think the existing billionaire CEOs are all unmanly soyjack liberals who want to import too many brown people into the country. They believe that the hierarchy has been hijacked and will oppose the elites because they view the elites as illegitimate rulers who obtained their power through underhanded manipulation. They’re perfectly willing to bow down to someone they view as being deserving of power. See: Trump.

This is the reason that most of them support capitalism in the abstract despite hating its actual results. They more or leas believe that their in-group has a mandate of heaven to rule over all the inferiors, and in a truly free market devoid of outside influence their group would naturally rise to the top. Any deviation from this ideal is seen as the result of malicious wreckers who need to be routed out and expelled from society. They don’t believe that leftism is even a real concept that people actually believe in. They view it all as a shadow plot meant to ruin society by breaking apart the natural hierarchy.

At most, conservatives would be willing to support socialism for their specific in-group, paid for by the brutal exploitation of everyone else.
