I disagree. The situation describe continues to exist both in the US and (more particularly) outside it. It's not always structured to make the employees utterly dependent and in debt to employers, though (usually for lower-skilled workers) this does remain the case, and is a key argument against "company towns" or other forms of employer-supplied housing in the absence of other competitive housing markets.
And the point you're trying to make about immigrant or periodic labor is precisely the problem that applies to serfs: they lack the means (or legal ability) to make their own discretionary housing arrangements.
For higher-skilled workers, who have other employment options, this typically isn't the case. Also where employees who operate under union or similar collective bargaining arrangements.
