It's not about in-groups and out-groups - that is far to general.

Historically, conservatism would have been strongly related to power structures.

In more contemporary terms it is as well, but not ostensibly about class.

There are no popular conservative movements that are mostly concerned with 'noble birth' for gosh sakes, or titles.

This whole discussion is ridiculoous.

Nobody is saying that 'The children of Senators should have special titles and special legal status'.
