No, eHarmony is not a site for rich people. It is one of the more expensive dating sites at the outset, but you can often get promotional codes for subscription rates that beat some of the other popular paying sites.

As for the income levels of those who subscribe, I have found a decent income dispersion. About a third make less than me, a third the same, and a third make more.

I am not going to speculate as to the income desires of female eHarmony subscribers, that's just asking for trouble. I will say that on other dating sites where income is listed along with income preferences, I have found that about half the women prefer men to make the same or more, and the other half don't mind if the man makes at least 75 cents to their dollar. But I would guess that women may be concerned that they would have to support a man, hence the desire for similar or greater income. But of course, some women may take issue with men who desire women with similar or more income, because that robs some of the "traditional" role should they want that.
