Apology accepted? But I do know what I'm talking about. Monopolies in a market economy can only exist if they've had no competitors and have met all of their customers needs and defeated all competition. Google is a monopoly, because it's something we're all generally pretty happy with. Even the slightest downfalls in Google lead to competitors taking advantage of that. Say data privacy for example, Google were subpar there, so Duckduckgo gained major momentum. Market competition will almost always prevent monopolies. Monopolies occur within our current model because state regulation, state taxes (including corporate tax relief) create what's known as a 'barrier to market'. Meaning it's far, far more difficult for a competitor to actually compete on a product level.
Most of our debt's occur because interest rates are so high, and why are interest rates so high? Because they're pegged above inflation, and why do we have inflation? Because governments bide time and bribe us with free things either funded by debts they've instigates, or by printing fiat currency. Which aren't market ideals, by any definition.
