I suppose that would be more convenient for English speakers, sure. Are you honestly advocating that non-English speakers learn fluent English so they can be paid less than native English speakers?
No, he argues that they learn English so that they get paid more than they are being paid now.
Technically we're talking about the same amount of money (more than they are paid now, less than a programmer in Silicon Valley) but framing does matter.
I think the point of having Noticias Hacker is that maybe it's not the highest possible aspiration to learn somebody else's language so they can colonize you.
[Note: I can't think of a less argumentative way to express that without being a lot less succinct. It's not meant as a flame, really.]
Addendum on rereading, because I think it matters: For a Pole to learn English to open up career opportunities has a whole lot less historical baggage connected with it than for a Latin American to do so, and this is over and above the fact that there are ten times as many speakers of Spanish as speakers of Polish.
