That's the problem, management is bad at their jobs. Management is so bad in the U.S. that everybody imagines they can hire their way out of situations rather than manage their way out of them.

For instance, when you tell people that you went to a Burger King and it took them 30 minutes to serve you a cup of coffee, the conventional answer is "it's hard to find good help these days."

That's a loser attitude on the part of management. Management hires employees, fires employees, trains employees, supervises employees, etc. If management does not take responsibility for your experience as a customer it is definitely the fault of management that you have a bad experience.

The problem has many facets but one of them is that few people are cut out to manage other people and our illusions about "meritocracy" contribute to an American culture that creates excellent foot soldiers but mediocre to terrible officers.
