I found the graphic below that shows the income for shops in the SE that sell fishing tackle. You can see a lot of them make less than $100,000 a year and that supports, at least in part, several people in most cases. Staying in business is tough for a small shop, if you keep the margin down where you are competitive and still make enough to pay the overhead, including salaries and take a little home to live off of.
