In 2013:
top 10% paid over 70% of total federal taxes 47% of all Americans pretty much paid nothing in terms of federal taxes
This also doesn't include the multitude of other taxes the rich pay (property taxes, use taxes, gas tax) and the fact that they employ many people that also pay taxes into the system (indirectly paying more into the system).
There are definitely some people using off-shore accounts, but it's not nearly as bleak as this article would like us to believe.
The US also has one of the highest corporate tax rate in the world.
If people are taking the risk and leaving the country with their money, we may need to take a look at our existing tax laws and figure out why they are taking the risk.
