I'd recommend to be careful when mentioning nationalities together with diminishing words ("dirt cheap") - even if it's not discrimination, it can impact your judgement and its validity.

For example, if you would have said "the market is flooded with dirt cheap programmers", the next question would have been: are the competent, therefore really valuable from a value per dollar perspective, or not? Once you mention their nationality, the reasoning goes elsewhere and you don't make your point (you do not follow-up on why they're dirt cheap, how this connects to their quality of work and why it causes the 60k cap).
