In our culture and economy, we place a value on the goods and services that we create or offer. Since others may not have the time or ability to create those goods or services themselves, we sell what we create to others in order to earn money. As we improve upon those goods and services, it becomes increasingly hard for others to replicate them, and thus the value increases. Similarly, as the demand for those goods and services increases, the value increases.
Unfortunately, the services offered by genealogists, including genetic genealogists, are severely undervalued in our culture. One of the most common explanations is that genealogy is a hobby and therefore subscriptions and research services are an unnecessary expense, and/or that people only use “disposable income” for genealogy. (Don’t say that outloud at a genealogy conference!).
