Really? Tell that to my back and two my two kids who’ve never been sick. With a free market economy, you would think there would be no chiropracters left if your assumption is true. Your purpose on this thread is to stir $hit up and get people arguing. I don’t know who peed in your Cheerios this morning but it wasn’t me.
Snake oil has always sold well in a free market. So do lottery tickets. So do the scams sold on late night infomercials.
The free market is wonderful opportunity to sell sorts of things - including snake oil and chirquacktic to gullible people searching for a solution to what ails them. Gimmicks work. Just look at all the stuff that gets bought because its “free” or “up to 50% off and more” or “guaranteed”.
