I don't really think wages are a proxy for opportunity as central banks can make currency worthless. There's computer science graduates in America who would take a job in their field for pittances just to be working in their field.

Well start! Half the startups in the 90s Americans built out of their garage.
People do not risk their lives and leave their families behind because they really love going to Cheesecake Factory everday in the US, it's because opportunities often flat out do not exist in their country for what they want to do.
Even among successful businesses founded in (currently or formerly) less industrialized countries, you will see that a huge proportion are actually state owned or backed (e.g. TSMC, Samsung)
Apple was founded in a garage.
Time for people in other countries to do the same for their own country.
A good product or a good idea will surface.
Your excuses fall on deaf ears.
Apple was founded after WWII (it would not exist today without a WWII victory).
Time for people in other countries to do the same what? War? More natives killing?
A good product or a good idea will surface tomorrow eventually.
But men being men will go where the money/food is today, no excuses needed. In fact no killing of natives needed either, so what's holding you back really?
Jury is out on this one. Japan has hardly any immigration yet their wages stagnated. Canada has a ton of immigration and their wages are also stagnant. Europe is somewhere between Japan and Canada, with also stagnant wages. Nobody disputes wages are stagnant, but the degree to which skilled immigration suppresses wages is an area where economists are unsure or even tilting towards a 'no' answer.
> if they're so good for the economy in America why aren't they good for the economy in their own country
There are so many jobs that are available only in industrialized countries. You won't find semiconductor fabs or airplane factories in undeveloped countries.
