> I don't understand why there's so many people in the comments defending non-competes. They have literally no value to society, or to individual employees. To go meta for a moment: I think that this sort of statement exposes a flaw that many of us have in debates. It's related to the "argument from ignorance" fallacy, but is not exactly the same thing. I take it as one of my priors that people at news.yc are intelli…
Against all that is the fact that California -- which, if it were a separate country, would be the world's seventh largest economy -- does just fine without non-competes. Compare the vibrancy of Silicon Valley with that of the Boston area, for example, which has a much older tradition as an intellectual center and is even better supplied with top universities; but Boston's tech economy has been dominated by large, ol…
Non-competes [0] are a tragedy of the commons. There's no incentive for any single employer, in a jurisdiction that allows non-competes, not to require them of most employees. Any employer who did that would be unilaterally taking a loss (the potential employees they can't hire because they're subject to their current employers' non-competes) with no corresponding benefit. But if all employers require non-competes, we demonstrably wind up with a less vibrant economy.
So, what is the libertarian response to a tragedy of the commons? Is it not to create and assign property rights so that someone has a legally defensible interest in protecting the common property? In this case, I would suggest that by outlawing non-competes, California has asserted that workers have a property right to the general skills and knowledge that they acquire by working. The word "general" is important here; companies still have IP rights to their specific techniques and processes. But companies cannot claim ownership of the worker's general knowledge; it belongs to the worker.
[0] I'm using the term as shorthand for "non-compete restrictions that don't require the employer to pay at least a substantial fraction of the employee's salary for the duration of the restriction".
