I'm pretty sure the meaning of that sentence is: "The people I am describing are more interested in impersonal objects than in people, and cope better with impersonal objects than with people".

There may be some truth in that. But it's entirely unobvious why it should tell us anything about those people's competence to offer financial advice, and (despite SanguineEmpiricist's some-of-my-best-friends response) it's hard not to suspect an attempt to exploit the halo/horns effect. (Warning: link in previous sentence is to a RationalWiki page; RW isn't super-reliable in general but this page seems OK.)
