It sounds like people are actually reading the article. Which means that the user experience is good. The bounce rate may be high, but the metrics that google probably care about are low: folks probably don't return to the SERPs and click on something else, nor do they need to refine their search. I don't believe that Google penalizes for single page sessions, but rather for bad user experience that causes a user to back out and do something else on Google.

I've also found that many articles on my site are not great drivers of direct revenue, but they are good link bait. If that page is generating inbound links to your site, it is likely well worth keeping even without direct revenue.
