Sorry my friend. I know you are being sarcastic, but this continues to betray not having enough exposure to the realities of business, employing people and the realities of businesses of different scales.
Most employees are not evil, incompetent or undesirable. And the same is true of most companies. As is always the case in the real world, a few bad players cause all the problems.
A simple example of this are police forces. The overwhelming majority of people are good, law-abiding citizens and most of us never interact with police in the context of criminal matters. Policing and many of the laws they have to enforce, exist because of a very small number of criminals and idiots that fuck it up for everyone else.
It's the same in the employer-employee relationship. There are a small number of shit companies and a small percentage of shit employees, and that's where friction happens. That's where laws and some of what is being discussed in this threat is a necessity.
Another example from personal experience. We manufactured hardware products. In this context, we had very expensive manufacturing equipment and tools. For example, we had a whole series of specialized crimping hand tools for various connectors. These tools range in cost from $400 to $1,200.
I cannot tell you how many tools were stolen by our own employees over time --tens of thousands of dollars.
Once again, it's a few jerks that cause the problems. You could trust most people with your life, all it takes is one or two idiots to change things. And change they did. We had to institute a sign-out system. We setup surveillance cameras in the assembly areas. In some cases we had to buy full kits of tools, assign them to individual workers and make them sign for them (meaning, they are financially responsible if anything goes missing).
So yes, a few jerks, both companies and employees, are responsible for loads of shit nobody likes, including, to go back on topic, such things as non-compete requirements.
I don't like it. I just happen to understand why these things exist because I have held many of these cats by the tail. A reference to my favorite saying: "A man holding a cat by the tail learns something he can learn in no other way" by Mark Twain.
One should never presume to understand anything until one has the experience to grab onto that tail and hold on for dear life. It is very easy to have opinions from an external perspective, in fact, everyone has them and they are all sure they are right.
