It wouldn't be 95%. The US is like 5% of the world, but it disproportionately contains the most qualified workers in many fields. Also, in many cases, even if a worker was somehow qualified, they would be lacking some basic skill like English proficiency or basic cultural compatibility, that would make them actually unqualified on net. But your overall sentiment is right. There are hundreds of millions of people who want to come to the US and make less than you.

It is also a fact that "most qualified" is fuzzy. It comes down to something more like, performance per dollar, or "culture fit", or some other thing. Unless you are trying to absolutely have the most advanced shit in the world at any price, "qualifications" or "talent" are not the ultimate factors. Having been in this industry for a while, most foreign workers obviously aren't "the best" like that. They're not even more talented or hard-working than the average American worker. But they usually work for less and the job gets done (roughly speaking), and their mere presence drives down everyone's wages.
