..and who the hell are you to determine where someone donates their money??

GP wasn't determining where someone donates their money. GP was pointing out that putting the Koch brothers in that comparison is ridiculous given their net worth.

Perhaps you should not publicize press releases and webpages detailing money you allocate "altruistically", if you do not wish others to comment.

(Throughout history in many cultures, people gain status by ostentatious gifts of wealth. Of course, that means you have to tell everyone of your benevolence. And as everyone knows, Koch uses his wealth — and shows like this — to wield enormous influence in politics.)

or lack thereof.

How much of your wealth do you donate?

The marginal value of money is small. If I had ten times as much money as I have now, I would stop working and travel a lot more. If then my wealth magically multiplies by another factor of ten, basically nothing would change.
