Keep living in a bubble. I have seen many h1b professionals here in US from various Dravidian states who revealed that mostly south Indian jobs are gifted to bimarus, while Dravidians seeking jobs in the north are disqualified just because they don't know hindi, of course it is not declared but that's the case.
Yes keep living in more bubble, in fact northern so called labors are eating up southern jobs but hey if you speak your northern masters will declare you desh drohi.
Yes now you are an expert of brexit too. While I have people in UK who tell me how things were becoming difficult when British was in the union. Basically UK providing funds to EU to bail out countries like Greece etc while getting eastern Europeans, Polish, Romanians, Bulgarians, Serbian even gypsies as migrant workers. Similar equation in India against Dravidians. But keep sleeping.
