The British public was totally cheated on Brexit. It's likely that a real motivator for the Brexiteer leaders is that the EU has anti tax haven legislation coming in in 2019, and that would have exposed them and their richest 1% friends to public scrutiny of the vast sums they export without paying tax on it.

My own thoughts follow
Everyone is used to voting for MPs. We do it regularly. If the person we voted for disappoints us then we vote for someone else next time. First past the post is pretty acceptable. Whoever we elect will be an MP, and they’ll do the same job, albeit in their own way. All the voting choices are very similar in nature.
Referendums are fundamentally different. For a start we use them only rarely. The choices are between fundamentally different things such as maintaining the status quo or going for very significant change. There is no way of reversing a decision save calling another referendum. Also, typically the risks all lie with one choice. Because of this, nations that regularly use referendums such as the Swiss use them late in a thorough process that flushes out all the information voters need and debates all the options before the referendum takes place.
On top of this, it is generally most unusual to use a 50% threshold in a referendum, the usual reason given for a higher threshold is that a proper mandate for change needs to be demonstrated. 70% is a common mark. Other nations are aware that a result close to the 50% mark is not a clear mandate with the big risk that it can permanently divide the electorate.
It’s this last situation we’re in. We had just about no proper evidence at all provided by either the Remain or the Leave groups. We are having an inconclusive result force fed to us by biased parts of the media and a clique of out of touch politicians, all of whose careers will benefit. Even business and the BBC are not debating or challenging the interpretation of the Brexit result, as they could and should. The result is in no way a mandate for change worthy of a nation of our standing. Where has single nation politics gone? Why is Britain at a stroke deserting the nations we are in so many ways closest to?
Brexit will be an utter disaster. People who think it's the best option really do need to read information sources beyond the right wing dailies whose proprietors are in the tax haven brigade. Their loyalties are not with the people of the UK. All nations friendly to think we're nuts. Only Mr Putin smiles as he sees the west weaken.
