Not really.
Either a contract means something or it does not. If it does not the entire structure is going to fall down.
In this case the contract not being kept is just a minor annoyance to those who got shafted. But once you get a reputation for not keeping your side of a bargain people see no reason why they should keep theirs with you. And once people get the idea that contracts can be broken at any point just because it can get very bad.
Agreements being made and kept are the foundation of all human interaction.
There’s another Seinfeld episode right there - the rental car reservation contract.
