The problem is that most people in the world AREN’T literally starving to death, or dying of easily cured diseases. The ones that ARE dying of starvation and dying of easily cured diseases are indeed the ones living under war, dictatorship, anarchy, communism, slavery, or a delightful combination of all of the above.
If we are talking about people literally dropping dead of starvation, we are already donating more than enough to feed them, and if they aren’t being fed it is because money and food isn’t the answer, they need the US military to step in to do the deliveries.
If we are talking about people in Argentina with crappy jobs and a crap economy but who have food, water, clothing, and shelter, then how much do I owe THEM? Their lot in life will improve as their country approaches the way things are done in the US, Canada, Japan, Australia, New Zealand, and Europe. But these people aren’t facing death, except in the same sense that everyone faces death. That’s why the “Bugatti” example doesn’t apply. People in Argentina and the rest of the functional third world don’t need more charity, they don’t need more food, they don’t need us to pay for their health care, they aren’t dying because we aren’t sending them money. Sure, they are poorer on average than we are, but THEY AREN’T DYING.
OK, but there are people who are actually dying. And those are the ones where more money would be only marginally usefull, and could easily be harmful. Wait, how could it be harmful? You give money to poor person A. Thug B hits poor person A on the head and takes the money and uses it to buy a gun. He then points the gun at person A and demands even more money. Money that ends up in the hands of the dictators and warlords and aristocracy is money that will often be used to make the citizenry of the country even more miserable. Look at how the oil wealth of the middle east has sometimes been a net negative for the citizenry of those countries, the oil money has given huge amounts of power to the dictators. Do we have an obligation to send in the marines? Even if the marines get shot at? What if the marines arrive, shoot the slaveholders and leave, but a new crop of slaveholders springs up to replace them?
In other words, the cases where we can help with money we don’t particularly need to help with money except in emergencies such as tsunami relief. In cases where people really need the help, we can’t help much with just money. What are we going to do about North Korea? China? Sudan? Somalia? Palestine? How many countries can we invade, overthrow the government, and administer without making the situation worse? We’re having a hard time–arguably, we’re failing–in Iraq right now. How much more can our military do?
Sending people handouts won’t work. Overthrowing their governments externally won’t work. So what should we do? How exactly does eating hamburger instead of steak help a slave in North Korea?
