In a truly capitalistic economy, there would be no regulations preventing competitors from coming in and creating competition. The propaganda doesn't have to be good when nobody understands what is and isn't capitalism anyways.
It's the same as a farmer secretly buying up neighboring already irrigated fields from bankrupt farmers, and not planting on them in order to be able to raise the price on their own crops, assuming that the cost of importing the same crops from elsewhere is prohibitive and there is no other readily arable land nearby (thus they have a monopoly on the local market). So it's cheaper for them to leave the purchased fields fallow, and raise prices, than grow more crops.
This is the type of predatory capitalist practices for which we need regulation in the first place.
