Should be obvious to them, slavery has been around long before the Roman Empire, the improvements made over the centuries for the taskmasters is noteworthy. Most of the slaves now have to provide and maintain their own cells, and without the cost of guards, has improved the bottom line of increased profits, and extra slaves not needed can be left to fend for themselves, getting handouts off the working slaves. Those who use large numbers of slaves contribute the least, everything they claim to own is paid for and maintained as a tax write off. Clearcut slavery and theft, legalized.
Since all claims of Property can be challenged, and nobody is getting away to the next world with a single grain of sand or a slave, it should clear that ownership is a dreamed up concept enforced by the rule of law, maintaining The Golden Rule, Those Who Have The Gold Make The Rules.
Well, the Self Government of Canada Without Borders, The Garden Party, is changing the game, and is replacing The Golden Rule, with The Garden Rule, Those Who Take Care of Garden, Makes Their Own Rules. No Military Required, unless of course they are properly armed with shovels.
