Remember also that just because you were born into a Corp doesn't mean you get to keep your Citizenship...
Meaning, if the Corp decides, for whatever reason, to cancel your Citizenship (and they can!) you are royally screwed. People like to think that Corps play by the same rules as governments, they don't. All they care about is the bottom line. So if Ma and Pa are Corp Citizens and work long hours to get to that position, but little Johnny is just a lazy dumb shit who thinks he can ride it out may find himself without a SIN, without a job, and on the streets.
Remember folks, As a Corporate Citizen, you only have the rights that the Corp is willing to give you, and nothing more.
No Free Speech,
No Freedom of Religion,
No Right to Self Determination,
No Freedom of Assembly
If a Corp wants to make sneazing on Tuesdays a capital offense, its becomes a capital offense.
Basically, Corps are Nations within themselves and as such have their own laws, programs, and social order. They do NOT have to follow the laws or customs of the countries that surround them. (For good or bad).
Now, the writers have never listed out what laws each company has or doesn't have, but you can get a good idea by looking that the Corp Culture, and the nation that they originate from. But just expect them to cut out anything that would cost them money, productivity, or threaten their bottom line. (Like Freedom on Assembly, as that can lead to "collectives"; which is too close to "union" for any ccompany to like!)
This is one of the hardest concepts for many people to grasp as it runs counter to many people's way of thought or the feedoms that they have grown up with and take for granted. You see this everyday as well in the current news as well. How many times have you read a story of someone asking the government to get involved when some family member goes off to another country and "bad things happen"?? The sad reality is that in many cases, your government can do very little. Their power and laws end that their boarders, and the other countries laws take over... (So, before you take that next vacation to the foriegn nation, do yourself a favor and brush up on their laws! it could save your hand! OR your life!)
