If you think about it, it makes no more sense to be angry at having been switched in the hospital than to be angry about having been born to poor parents in the first place. Adding the random element of the hospital switch doesn't make the underlying process any more random than it already was.
And of course while the single data point of the fact that the man ended up being a truck driver, while his counterpart became the president of a real estate company, proves nothing, I do find it an interesting anecdote. People who want to downplay the importance of class delineation like to point to the extraordinary people who rise from poverty into success. But my hunch is that given two individuals of ordinary moral fortitude, the one born into a rich family will tend to be pretty successful, while the one born into a poor family will tend not to be.
