Let me ask you this. Have you heard from each individual who has gone to Korea and other places for employment? Have you heard each of them bragging? Then why are you giving the whole group a bad name?
You might have few relatives back home, if not your whole family. Remittance money contributes to 20-30% of Nepali GDP, so one can deduct that 1/5 Government operating budget could come from remittance (math is not as straight forward ofcourse, but in a ballpark). You can make a point that this is one sector that has been a boon to the country, why are we hating the contributors of this sector?
Let's look at it from the other angle. What are they complaining about? Their complain seems logical to me; you already gave the exam and showed your proficiency, why then you have to do it again? Say you took a midterm test and even got good grades. Now the school says you have to take the test again after few months for no reason. Wouldn't you be mad? Now multiply this scenario by 10 times where livelihood of somebody is involved.
Okay, I went on a lengthy rant, but I just wish we stop blaming the working class. Give them a break even when they are bragging, they are the biggest contributor to the country and deserve a better treatment from the country.
