I don't know any examples but someone explained some pulling up the ladder trick: An existing business you can implement nice things gradually over a long time and have them written into law. It seems very nice but the future business will have to implement everything before starting.
No, the idea is that existing businesses will lobby for the government to prop them up. Politicians are inclined to think it’s reasonable to protect jobs and such. But maybe if they let the business fail, what rises from the ashes would be even better.
