Throughout history, the UK has been one of the most powerful, successful and wealthy nations on earth. Which is amazing considering its size. But no country or person has ever become strong by allowing those in a weaker position to take more than they can give back.
I think a large % of people who want to remain, do so because of fear. Fear of the unknown, fear of the initial change, and fear caused by propaganda.
But this isn't a suitable place to start a debate like this. Nor do I respect the attempt at using it to sway people's opinions. When it comes to the actual truth of the outcome, time will tell.
