>While this is generally assumed to affect low-pay, low-skilled jobs, it can affect those in IT too.
Trump and a Brexit will harm low-pay, low-skilled jobs for different reasons ...
Trump is a republican, akin to Conservatives and New Labour in the UK or LR and PS in France, all they want is to enrich their already rich friends, they have zero incentive to do otherwise ... that means low-pay gets even lower-pay (cf zero-hour contract in the UK).
A Brexit will not stop EU Europeans (Poles, Czechs etc) from entering the UK to work, that simply is a lie (unless you "really" wanna break treaties, in which case you will have some serious economic troubles, they will NOT allow you to pick and choose once more), what it will do, though, is cause many multinational businesses to move over to the continent... Besides, all the migrants from outside the EU who are currently in France will end up in the UK, because France has said: Brexit means we send them over!
IT will be especially affected by a Brexit. Either way, I do not care, I no longer live in the UK and could not care less what you decide doing ... I'll never go back anyway ;-).
