People who are interested in conservatism are interested in conserving what we have. Therefore almost by definition, conservatives are going to be people who society is working pretty well for. Those with stable jobs, with property and wealth, with no or minimal discrimination, and with no reason to change the status quo. It's not a massive surprise, for example, so see Muslims who are far more socially conservative than the most ardent UKIP supporter become left wing when they live in a society where they're a minority and society doesn't work in their favour (that's a badly worded sentence - I don't mean to suggest that all Muslims fit into this category, just that I've seen some that are very socially conservative who support Labour).
