I don't agree - there is a subset of people that criticize meritocracy as a concept because they believe the idea of 'merit' is inherently racist and classist - if you start at a different level, it becomes more difficult for you to accrue 'merit' and so that needs to be balanced and taken into account. Some people believe this is much more important than hiring or promoting on 'merit'

And in case I didn't make this clear, that was just a quick dump of views that I think are generally considered conservative. Real life is much more nuanced than a list of bullet points. I fully agree that there are, for example, people who want tougher immigration laws but otherwise don't consider themselves conservative.
