Doubling McDonald’s Salaries

Let’s say McDonald’s decided to double all its salaries, so that the entry-level wage became $16 an hour instead of $8 an hour. Why would McDonald’s continue to employ their $8 an hour workers when instead they could hire “better” workers who are worth more? (And those of you who think that the skills, linguistic abilities, experience, intelligence, etc. of fast-food workers makes no difference in service don’t eat in McDonald’s much.)
