When I was a Director I frequently beat my staff. I chained them up at night and made free with their women, keeping the resultant children as my own future slaves if it pleased me to do so. I kicked a couple of the men to death (they made an inadvertant error), but fortunately for me they survived 36 hours in horrible pain so at least I need fear no biblical injunction. Now I am an employee my bosses do the same thing to me and my fellow wage-slaves. Truly, paid employment is just like slavery.
But I was always sure that I let Hebrews go before 6 years were up (well, actually I sold them on after 5 years).
And don't get me started when it comes to tax inspectors. Taxes are just like slavery too (according to the cretinists).
