How does one cope with discrimination (nationality, pay) when looking for a job? Has relevant work experience has become irrelevant?

In some cases, the selection will be done on a pay/race reason. I face this issue, as my expectations are higher than other nationalities, even my expectation are backed up with years of experience and hard work, some employers told me they can hire someone from other nationality (i will not name the nationality from respect) and pay half of my requirement. So yes in some cases experience doesnt matter, all that matters is to accept a low payment .

Knowledge & Expertise supersedes all of the above. There can be a case where a candidate does not have control on the matters, May be that is not what GOD has selected for your, MOVE ON.
