To start the ball rolling, in the UK the situation about unlawful deductions from wages was governed by the "Truck Acts" from long long before the time that the USA declared independence, and therefore those Acts are likely to have been continued into US common law - until repealed if they ever were (much as the US originally followed old UK copyright law flowing from the Statute of Anne). In the UK the relevant law is now subsumed into the Employment Rights Act 1996 as amended.

I imagine however that US law did change, given the number of customary references to "the company stores".
