Ceteris paribus it is better to live in a country which can generate lots of technological progress than in a country that cannot.

So you'd be better-off if SpaceX and Google were Chinese companies?

Also, a lot of the wealth from the tech industry does spill over to the larger community. You're strictly better off having it. If the US had just stuck with their 1970s economy on the theory that any new industries wouldn't distribute their benefits equally, it would be vastly smaller, less powerful and less wealthy. Surely that's obvious?

Ah the famous trickle down rebranded as "spill over".

"Trickle-down" has become a thought-terminating cliche.

Of course your country is better off if you have successful companies and high-income jobs.
