Is there a demand for a meta description writer?

I have already developed this habit of writing a meta description above the title of the articles that I write for my clients. I do that regardless if my client is concerned about on-page SEO or not.

Here's my question. For webmasters out there, do you find a meta description helpful as far as your on-page and off-page SEO strategies are concerned? If not, why not?

I am very interested to know so I can decide if I should retain or drop that automatic meta description above the title of the articles that I deliver to my clients. Thank you for sharing your thoughts with me. I appreciate it.
