It's about two different phrases, and both have similar compete rates, in overall.

In fact, some no-money phrases (that rank high) have more competition than the money phrases (which don't rank as high).

Also, is it possible that the information articles are getting more inbound links, perhaps from better sources, than the money articles are getting?

good point; but it appears that the IBL is the same. As mentioned earlier all phrases are treated equally in regards to content, material & layout, so they should both deserve the same inbound link rate.

Internal links in the body text are looked at when determining keyword density. Navigation links are not taken into consideration; in fact they're almost not there.
