Barriers to Entry – Basically, if starting a business costs too much or you need special permissions, new players just can’t get in the game. It’s like an invisible wall keeping the competition out.

Predatory Pricing – Some companies drop their prices super low just to crush smaller competitors. Once everyone else is out of the way, guess what? Prices go right back up.

Government Policies – Sometimes, the government unknowingly helps certain companies by giving them perks or making rules that favor them. This can end up giving one company all the power without even trying.
