If capital is planning on being this dumb, as labor I have no problem whatsoever relieving them of their monetary burdens.
This morning, I went to a bakery and ordered a blueberry muffin. It was fresh and moist and delicious. I was satisfied. If it had instead cost the same money but been dry and crumbly and had a taste of old socks, I would have considered myself to have been "ripped off". So now, you ask:
> Why does having a contract eliminate the possibility of getting ripped off?
Every step along the way to having a signed contract normally involves an increased awareness of expectations by both parties. That's what the contract is. And the moment of signing a contract is an intentional decision to move forward with the transaction as specified. It's certainly possible to subvert the normal process in such a way that you obfuscate your intentions, but even then, the results of your intentions must show up in the contract language itself, or they won't count. Unless someone is holding a gun to your head, or you're not intellectually capable of entering a contractual relationship, the moment of signing your name to a contract is a moment where you are affirming that you aren't being "ripped off", that you've considered the terms and are willingly agreeing to abide by them.
Perhaps it's still possible to do all that and consider yourself to have been ripped off. And perhaps your examples are good examples of such cases. But if your board or C-level executives sign a contract for employment of a high-level executive which includes a 9-figure deal for compensation and they don't have more awareness than a poor person going to a car lot, they didn't get "ripped off", they're ripping off the investors or shareholders by collecting whatever salary they're collecting.
IANAL, also not a C-level exec, also not particularly smart about how crypto "works", but this all seems like fairly obvious stuff.
[EDIT] But perhaps it connotes differently outside American English? That could be.
