People who complain about quality control probably are very short sighted in general. Quality control is basically insurance. You buy insurance just in case something goes wrong, like getting sick, into a car accident, or your house burns down or floods. It costs money in the mean time, and you may never need it. If something does happen, you’ll be glad you spent the money then and saved in the long run. Quality control is definitely a protection plan for your future. Big companies can survive lawsuits but they shell out billions. Small companies can’t afford to do that. Spending a fraction of the cost on “insurance” is the best way to protect your future endeavors.
