I think it is amazing to see the life and works of one person dedicated to service to others. Quite a refreshing difference from the leaders of our country. The fresh air of compassion at times enters our own life and we see a passage way to spiritual enlightenment that opens momentarily for us. A moment to never be forgotten!
I think they are two different levels.
Amma carries out her service in the highest spiritual levels, without ego.
Trump carries out a service of fundamental importance and maybe, I hope, he'll succeed in making things straight again in America. He has ego in his motivations of course, but I feel he has developed a sense of altruistic mission. His novel sense of having being chosen by God for this mission to resuscitate America from the former abyss she was plunging into is fueling a genuine will to serve that is beyond pure egoism and narcissism.
