If quality is the same, that is exactly what will happen. You are already using software, iphones and TVs built in 3rd world countries for $5 a day.
Any evidence supporting your statement? Or is it just pure anecdote. To counter your point: there is a long list of writers with accolades in writing (in English) who are not native speakers.
There are people who are just poor at language, native or learned. Also, there's a class of errors that only exists among 'native speakers', the most grating to me, is "would of"
its completely incomprehensible.
With love,
Your non English speaking 3rd world citizen.
I'm sure you can write English very well and there are probably many people like you (maybe even yourself) who can write far better than I can. It's just in my experience such people are few and far between where outsourcing is concerned.
