A sinister modern situation demonstrated in this video masked in humour.
We probably don't realize it but reimbursement of receipts is the new form of exploitation, especially of white-collar workers these days. Taxi reimbursement gives you an illusion of company's compensation to your overtime hours. Similarly, restaurant/ client receipt reimbursement increases your "spending power" but not your salary ('wages' if you'd like), furthering your illusion of how much you are compensated but actually these transactions do not benefit or compensate for your labour hours at all. These are things you would otherwise not spend on anyway.
Reimbursement is sold as a welfare benefit for employees, but it is not. It is another instrument of the capitalist system to exploit workers, especially by a more perverse, self-inflicting form of exploitation. The enemy has become ourselves and our lack of awareness of how exploitation can manifest in different forms.
