Sorry this description is a bit confusing but i couldn't really think of a way to phrase it properly :)
most economists believe that deregulation has the potential to be helpful because the fact that things aren't regulated by the government increases competition in people selling the same wares, which normally ends up lowering the price of that specific good and/or improving the quality of the good drastically (which means more people will be buying, it whatever it may be, which is good for the economy)
