Capitalism has competition and ultimately the idea is by having open market places you obtain the best product, most efficiently made and cheapest to deliver to the most people.   Bidding on higher prices might be liked by traders but the product is for the people who use it and they want the lowest price, this dynamic is seen in market and the reset is totally normal.
