It's a common thing in most of countries.. I guess only developed countries are where "clear rules and law" exist for labour and workers.. so, they can't exploit easily.
But here, it's like no one cares.. unemployment rate is high and people willingly do job for less money.
You're wise enough to say no.. I hadn't learnt it at that time but now I know what is right and wrong.. so, yeah... getting educated about it important for all. Agree with ya!
