>I have never seen an H1B job posting that was truly for "skilled labor that an employer couldn't find a citizen for."
What exactly do you mean by these "H1B job postings"?
Job postings do not advertise visa sponsorship. A large portion of the H1B applicants were already working their job for some months before applying, under the OPT program. Also, a quarter of all H1B visas are only given to applicants with verified advanced education degrees (Masters, PhD, etc.).
To be clear, the H-1B does not require a test of the labor market (unless the employer is "H-1B dependent"). That's only required in the PERM/GC context. The standard is whether the offered job qualifies as a professional/specialized job and whether the individual has the right educational background.
