Being a Personal Assistant

I have been working at my new personal assistant job for about 3 months. At my old job I was respected, not so much here. My old boss was kind and understanding. The reason I am now at my new job is because my old boss decided to sell and just like the new president's cabinet, the new guy did some spring cleaning. I was lucky to find this job, but I am not happy. My old boss would say thank you, my new boss just grumbles about and without so much as a word sends me e-mails. I don't think I even heard a Welcome Aboard from him. I know that as the boss, he is not obligated to do anything, but it still sparks the question: "Is it better to be Respected or better paid?
