"This is an article trying to make an ideological case rather than to discern truth."

Generally Economist is unashamedly political. That's what makes it so good - they don't try to hide the fact that they take a stand. They give you the facts and their arguments, and then it's up to the reader to digest it.

If you disagree with some of the points, I suggest you send them a letter. The letters section of Economist is one of the high points of the magazine as well - they publish rebuttals and corrections no matter how far they stray from the magazines core claim as long as the letter is well written and sanely argumentative.
