I think a good way of calculating their sentence should be in lost Franc-years. That is, calculate all of the lost wages they didn’t pay and force them to serve as many years as that amount would make in minimum wage. If they paid one staff member 1/12 of the minimum wage for one year, then that’s 11 months of gaol. If they paid 10 staff members 1/12 of the minimum wage for one year, that’s 9 years gaol. Take from them (in time) what was stolen from their workers. That’s the only way they’ll understand what they’ve stolen, because they have no value of a dollar, rupee, euro or franc.
