I will grant the critics that the "art" at these sales is produced for volume sales and profit. However, most water color artists produce prints, are those prints still art? Many crafts persons produce multiple works with only slight variations one to the next, basket makers for example, does their work still have creative value?
The pieces you find at these sales will very likely not be ultimately notable works, but don't so harshly discard their creators labors. Take these pieces for what they are, decorative and affordable.
