This is obviously wrong. If their methodology says that Caltech is in the bottom 2% of US colleges, then one concludes that their methodology is worthless, or at least that what it's predicting is not very closely related to the quality of the education provided. I suspect that many Caltech undergraduates decide to pursue grad school and academia, which is not an especially lucrative career, and which is probably not highly corrolated with political leftism or "reefer madness".
I can also tell you that my friends at Rice who were looking to make a lot of money after they graduated, by and large succeeded.
In summary: Bullshit.
