Stuff should cost however much a buyer and seller agree on. That's how a free market works. If a buyer thinks a seller is asking too much for an item -- whether it's a sandwich, internet service or a house -- the buyer does not have to agree to the price. But if another buyer agrees to the price, the seller will sell the item to that buyer. If no buyer agrees to the price, the seller will only be able to sell the item if they lower the price to a level where a buyer agrees to buy it. This is how a free market works. Items are only sold when a buyer agrees to pay the requested price. (If you want items to be sold for low prices, you should be the seller... then you can sell your items as low as you want.)
this is also why businesses want to be a monopoly so that they can charge what they want and people have to pay it. Then the same people who want a free market economy complain to the government to make them lower their prices
