So much information in just one WSJ paragraph

Below is a paragraph from an editorial in today's WSJ. I broke it into a series of sentences. Look at all the infromation it contains.

Unlike grades K-12, government aid for college is generally voucherized, with Pell grants and the like going to students for use at the public or private school of their choice.

As recently as the 1950s, the Ivy League was a place of economic and social privilege.

There were often not-so-secret quotas for Jews and Catholics, and minorities had little or no chance of entering.

Now their student bodies are nearly as broad as the country itself -- and certainly more so than their faculties, which thanks to tenure and intellectual conformity aren't diverse at all.

Why can't the New York Times editorialists produce such fact-based and informative paragraphs instead of their usual ad-hominems, most notably their Bush-bashing?
