Human Nature

[The Grand Nudger]

Just as you say, people have limited leverage on their own human impulses.

Or they simply don't give a shit. I don't really believe that people want to be decent. They may want others think  that they are decent but that's quite the difference.

Plus, in a world of suboptimal choices as Nudger pointed out, if we fed all the starving poor people we might just end up with even more starving poor people.  We couldn't change their problems with poor agricultural environments and over-population.

Or we would simply pay more for some goods or go without some luxuries. This is irrelevant however as I don't see worldwide protests against money being wasted on frivolities when there are thousands starving.

A very large number of the starving and malnourished people of the world have money for food.  A surprising number of them are in agriculture.  More than enough food is made.  Far more.  Hunger in the world right now mostly boils down to market disparities.  That it doesn't make financial sense to send (or sell) a product to a place where you could only get half (or less) the dollar amount for it as some other market.  Point being, continue to spend on your frivolities...it really isn't what's making people hungry.  Alot of the time, your frivolities are the only reason they have any money to buy the odd bit of starch that comes along.
