Being worried about the world

Note(Disclaimer) : This is just from my perspective, I'm not declaring that anything is either wrong or correct.

Now the world has been changing significantly.
I, today, would like to focus on Brexit and an election held a few days ago.
Personally, I do not really care about who is gonnaing to be a the president usually most of the time. (I am not really a political person)
However, this time it hasd a different meaning, as it was an extremely important one for the future of UK, EU and their (state-owned?)companies based in UK.  

If you kicked out all of the EU citizens from UK, who between the remaining people would be willing to work in a very hard condition?(<-kono imiwa aimasuka).
Who are the ones actually contributing to the country? Let us remember before being it's too late to realisze.

Thanks for reading this and for your correction in advance!
