The term "barriers to entry" frequently has a negative connotation, in that people perceive it as unfair and against the spirit of free markets for barriers to entry to stop entrepreneurs from pursuing their dreams. But what about barriers to entry when it comes to air travel or other industry where lives are at stake? As pretty much always in the world of economics, it's... well, complex. On the one hand, nobody would want to live and do business in a world where barriers to entry for pretty much all industries make it impossible for startups to find their place, leading to monopoly or oligopoly situations where one company or a handful of players enjoy a competition-free ride. From definition to examples, you will understand what barriers to entry are all about. In other words, barriers to entry have been explained in an unbiased manner and (especially) in a way which leaves little room for interpretation. Through sometimes outrageous/funny examples, you will undoubtedly understand what barriers to entry are, why you should care and what (if any) role they have in the financial ecosystem.
