Fewer people go to college than you think

He proved his point by hiring me [2] for a job. At that point in my life I had no degree, but I had just spent eight years in the Marines, and had done everything from programming computers (badly) to micro PC repair and LAN administration.
[1] Who was, improbably, interviewing me for a job. Long story.
[2] Sort of. He called me back said he _would_ have hired me but the company had just gone into Chapter 11.
These days, about 68% of high school graduates end up in college (different stat than the percent that graduate)... So the "misconception" that most people go to college after high school is actually completely correct. Source: http://www.bls.gov/news.release/hsgec.nr0.htm
"go to [some] college" (68%) and "graduate from college by age 25" (27%) are COMPLETELY different statistics. Lots and lots of working class people graduate with decent grades, go to the local state college, don't fit in (or party too much), and drop out.
And going to 3.5 years of college and dropping out versus a BA makes a HUGE difference in career outcomes later -- it is a discontinuous jump.
The original article is about all people "25 and older", not "25".
The census data he's quoting is "Bachelor's degree or higher, pct of persons age 25+, 2005-2009":

So, of high school graduates, only 37% (68% x 55%) get a Bachelor's. And only 85% of young adults graduate high school!

85% x 68% x 55% = 32%
So we only expect about 32% of 30-year-olds to have a Bachelors. That means that there's only about a 5% difference (as in 32%-27%) between your data (about current yound adults) and the OP's census data (which is weighed down by old people). So I think the OP's conclusion is more or less right.
That said, my prediction before I read the article was 25%, so I wasn't too surprised. This is a classic case of what happens when you're surrounded by people who are a lot like you (i.e. educated): you assume everyone is like that. And there are a lot more educated people with blogs than uneducated.
