Conservatives and the Golden Rule(s). What’s the deal?!

It seems to me that there are two golden rules that are in direct conflict with each other, and I’m not sure how conservatives reconcile it.

Rule 1) “Do unto others as you would have them do unto you”
Rule 2) “He who has the gold makes the rules”

The real question is, why do “conservative” and “Christian” show up next to each other? They should be mutually exclusive! Conservative philosophy teaches that you should take care of yourself and that money is the only force capable of incentivizing people to act other than in their own best interests, and amassing piles of it is the proper approach to life. Christian philosophy teaches that “the love of money is the root of all evil”, and that you should be nice to people because it’s the right thing to do.

How do these people resolve these two things?! I would very much like someone to explain to me how these two philosophies are anything other than mutually exclusive. They are matter and anti-matter, they should not be able to exist together. I can’t figure it out.
