I don't think this is accurate. In the US, the onus of abuse reporting is on the employee. You can abuse your employee knowing that if they report you, you'll know they reported you, and can carefully torpedo their career knowing the employee has a very high bar to legally prove retaliation in court.

Can? Yes. Do? Not really, not often.

Abuse is possible! It’s just not common, not in the sense of “servitude” being slavery or some other kind of abominable condition. Maybe you get the shit work, maybe you work more hours, but let’s not pretend these are the salt mines.

Words have meaning. When we use 'indentured servitude' in the modern context it means that it is not easy for a h1b worker to change employers as easily as someone with residency or citizenship. This is irrefutably true.

When people cannot easily change jobs they deal with worse working conditions and worse pay. I have seen people work for the same employer for over a decade because they would have to restart their greencard process otherwise.

Words do have meaning, and that’s not what “indentured servant” means, at all.

What an oddly pedantic hill to die on...

I'm not dying, and this is your hill, not mine. Words have meanings, yes? Then use those meanings.
