The Remain campaign never made any positive points about staying in the EU (apart from a few in the Labour party talking about workers rights, but they got about 4% airtime and very little newspaper coverage). The vast majority of the Remain campaign was all about the terrible consequences of leaving.

The Leave campaign was a mix of fear of foreigners, fear of unaccountable bureaucracy and a vision of a Britain that had "taken back control".

The purely negative vision lost.

(There are also those that say that the Eurozone was doomed to failure because of the imbalances in the countries involved with no mechanisms to rectify those imbalances - making the fact that the EU stepped in and replaced two democratically elected governments an inevitability. So it engineered a bad situation then punished the losers in that situation for falling into it. But I don't know enough about economics to argue that point)
