I can never follow this type of reasoning. Is it sad when Little Leaguers want to win their game? Because that means another team must be considered loosers. Is it sad when people spend all their time in a lab and ignore their family while developping a life saving drug? Because for those few years they probably failed at parenting. Is it sad that someone is willing to take less salary to support a cause they believe in?
It isn’t sad.
Working in a position that not only provides some financial support in the form of a paycheck, but also an outlet for directing resources to a cause one supports is simply part of the mechanisms. Note that I am not saying that taking advantage of someone, or bullying someone into, or misleading people as to the cause they are supporting is alright. Those are examples of fraud.
But that people figure out ways to combine their time and resources to advance their private needs and public causes, literally everyday that they breath and walk on this earth, is simply how we all live.
