"stars"...are playing a game just as...politicians play a game, and for...the same self-serving, egotistic reasons.
When the majority of voters understand that politicians--like "stars"--are self-serving, the nation and the world will become far safer.
Those who claim altruistic motives--especially those who "want to give back"--are the worst.
When the electorate realizes that the politicians in Washington are NOT their friends but are a parasitic, ruling class, we can all sleep more peacefully.
If Madonna et al. raised the public awareness of this--even just a little bit--perhaps they unwittingly did the world a service.
Altruism only exists in times of excess or extreme crisis.
