I did a little math, and they have me working about 6 hours a day, 5 days a week to get my hourly rate (this includes vacation and holidays). A little off, if you ask me. The math they use to determine how many people are “better off than you” appears very wrong, too.
According to this article, there were 8,200,000 households in the US that had a net worth of more than $1,000,000 US. If you put in that you make $1,000,000 US per year, it puts you in the top 0.001% in the world, which I doubt is true. This would be “about” true if the 8.2 million millionaires in the US were the only ones on the planet. But they are not. Using the current exchange rate of USD into Euros of 1 : 0.8283, I compared what it said I made in USD to Euros. It turns out that I am much “wealthier” when I state my income in USD than it does when I state my income in Euros (to the tune of I am suddenly richer than 4,400,000 people when I earn dollars).
This site would be more effective if they cleaned up the math. I believe that it is possible that the site is intentionally skewing the math to make people living in the United States feel more guilty, which might make them more likely to donate AND donate higher amounts.
To be fair, people who have decent jobs in the indutrialized world are very well off. It certainly does cost fewer dollars to live in the undeveloped world, but you don’t have the housing, medical care, clean water, abundance of food, transportation and communication that you do in industrialized countries. That is the trade off. Which would you rather have?
