Idea
The Pun Tyrant
In that case, to give a basic rundown of the idea (and keep in mind, my understanding of the subject is still pretty rudementary, I'm just another economics college student) the changes to an economy over time is that more money enters the economy which means everyone has more money which means the prices of products go higher because people can pay more. The value of the product’s relation with the money spent to buy them doesn’t change overall in an economy with no regulation, though the money does increase and technological advances still mean the people get more value in their hands.No? If it was rhetorical that would mean I have the answer to it. Which I don't. I'm just trying to phrase the question.
The issue lays however in things like international trade (because the value of a given currency, especially with speculators around, can become overblown) and what happens when companies abuse their market presence. When a company can afford not to uphold a contract you know you have a problem in your hands. That said, it's not like even without regulation a company who holds a monopoly is unstoppable. Fads go away, innovation comes, and over time as long as there are people being abused by a company's pratices, there are clients whose best choices will be that company's competitors, even if they have lesser products or are just a small business.
You probably can figure as much, but the world of finances and market competition is extremely complicated. The "natural" solution for the economy's balance, this is, what brings a market closer to a balanced free market without government interfierence, is simply time. But it can take a really long time, especially if the company can essentially act like dictators and use other means than economic ones to "deal with" the competition, like i suspect they would in your setting.
On a side note, one shrewd strategy certain monopolies employ in real life is to attempt to disguise themselves as several companies in the eyes of the public. Many large corporations opened several small businesses controlled by the large corporation, so to the public you have all these different shops of similar products when in reality they all belong to the same group.
It wouldn't fool the government or other companies, but it could help quell public outrage, thus helping the scenario you are trying to achieve be more plausible.
