(Cross-post from my other blog, Freedom is Moral.)
You really need to check out the graph of GDP per person for the last 1,000 year in the U.S., Europe, and the rest of the world.
Then you need to ask yourself why everyone on the planet had a horrible income level since forever until around 1800.
Then you need to ask yourself why the income per person has gone up so dramatically?
Why has income in Europe gone up so much more than the rest of the world?
Why has the per person income in the US gone up even faster and farther than Europe?
How we can continue that trend for everyone on the planet?
Hmmm. I wonder if there are some reasons for the trends in that graph?
By the way, there are answers to all the above questions.
Finding the answers and repeating the cause of the skyrocketing GDP is a moral issue.
