How should I cope with my arrogant brother?

Some people always be a jerk. If he comes over state that you have some errands or while he visits tell him you are going to go see some old friends ask when he will be leaving and state you will try to get back to say goodbye. As for your job maybe it is time to find a new one even if you have to go to another city or country.......life is to o short to be around mean idiots. Why some people get a free ride I dont know but it is all about Karma someday he will be in the pickle barrel, it always happens.............good luck
