I have only seen anecdotes while the law explicitly states H1Bs should be paid the prevailing wage or above.
On the other hand, for some shady companies that are set up as contract shops, then I'd not be surprised if the wages are lower than average market rate, but I have never worked at one, so I might be misleading by even mentioning this here.
Authorities do enforce H1B provisions proactively.

Will that apply to every law in society or just to H1B laws?
Despite absence of consistent heroic efforts, we don't see widespread criminal activities.

The H1B laws are harder to enforce than most laws -- or so it would seem to me -- because the question of whether there are Americans that are able to do a particular job at a particular workplace depends on many fiddly details that only the managers of the particular workplace (the prospective defendant in any enforcement action) would know.
When lawyers working on Capitol Hill are serious about stamping out a behavior, they write laws that are easy to enforce (unambiguous, not relying much on human judgment). Something as vague as, "as long as there are no Americans qualified to do the job," suggests that whoever wrote that just wants to reassure critics of the H1B program without caring much whether H1B workers actually displace American workers.

H1B devs at FAANG companies are paid far more.
Your question is why is it wrong to depress wages? Yeah, really tough question.
Now consider OPT visa workers which are being paid even less, plus companies get an extra 8-10% discount because they don't have to pay Social Security and Medicare. There is no shortage of skilled workers here. Only corporate greed.
