Will Brexit cause social unrest as well as political unrest?

Brexit, without a doubt has been one of the most perplexing political decisions in 2019. However, all the people 'for' Brexit tend to ignore the social unrest and the political unrest which can be caused. A simple refrendum cannot and should not be enough to decide Britain's future. If people keep ignoring the unrest, Britain may not even hold some of the power it holds now. Many economists predict a signoficant increase in poverty levels in the UK after Brexit which may lead to high crime rates, etc. Also, the political body may tumble as they may not hold enough power to neutralise the country's problems (at least some of them) as the number of problems will significantly increase.
