There's so much wrong here.
> The main idea of the non-compete agreement is that employers want to stop people from walking off the job and taking trade secrets to rival companies. If companies weren’t able to secure those protections, they’d need to pay lower salaries, and we’d all be worse off.
No. If companies couldn't coerce workers to stay with them against their will, then they would have to pay better and be better employers. And we would all be better off.
> But suppose instead that innovation is difficult. Lukas Walton has a net worth of $22 billion because his grandfather founded Walmart. If he decided he really only needs $5 billion in life and is going to plow the other $17 billion into a massive R&D effort, how much innovation will he really generate?
A huge amount. Plenty of people set up research institutes or new departments at universities that make giant leaps forward. See Paul Allen for example.
> To a considerable extent, this hinges on poaching. Silicon Valley was a good place to grow Facebook because fast-growing Facebook could poach from older tech companies.
I wish people would stop with this anti-labor language. Poaching? That's ridiculous. It starts by offering people a better place to work, with a better mission, better people, and more money. That's not "poaching".
> And Silicon Valley is a good place to launch a startup today because you can poach from Facebook.
That's funny. FB and other companies offer far more money than most startups can afford. That's not why the Valley is a good place to launch a startup.
> One of the big, overarching problems of our time is that productivity growth has slowed down sharply from where it was during the post-WWII decades.
The overarching problem of our time is that productivity no longer means higher salary and higher quality of life. Productivity keeps going up, but salaries stagnate. What's the incentive to be more productive?
> In the early days of the computer industry, Silicon Valley was rivaled by the Route 128 corridor (this is a road through the Boston suburbs) in Massachusetts as a hub of innovation. But California won out decisively here, and many people think the lack of non-compete agreements in the Golden State is part of the reason.
There's a lot of debate about this. And now we're running the decisive experiment! MA just basically killed off non-competes (1 year limit, narrow scope both in terms of work and geography). Let's see if the biotech industry stays.
