Monopolies are generally bad for society. As well as a lack of competition, they tend to create higher prices for consumers and are believed to ultimately lead to less innovation.
In a monopoly, the government allows only one person to provide a certain service. So yes, people tend to dislike monopoly. Example: These guys are selling grain. One guy sells it for three bucks, another guy four, another guy five. Nobody can afford five bucks, so they stick to the three and four dollar guys. But the five dollar guy is cousins with the king, so the king makes it illegal for anybody to buy any grain except for Bob, the five dollar guy.
But when people can only buy from Bob, he spikes the price up to ten bucks. No one can pay that, and they die.
What about the advantages? Well, Bob, the five dollar guy is really the only guy who benefits. People can't pay insane prices, which means that the more people you have selling something, the better. Better for the buyers, better for the insurance dudes, and better for the sellers. You shouldn't try to choke production of a product for your company, that just means that nobody can afford to buy from you, meaning the guys who spiked the prices are stuck with a bunch of vacuum cleaners or spatulas.
I like that you have Bob making people die because of his prices. I like that your saying Monopolization is bad. I think that you could put a little more about the topic, but beside that I think it is flawless.
