This would be a good thing.
Ah, you don't have retirement savings or investments that you'd like to avoid another market crash with?
The UK (at best) will have slowed growth, but more likely fall into a recession in the next couple years as a result of this vote. The market drop today will be but a small part of what is seen should other countries also disrupt the global economy.
I'd wager that unemployment in the UK goes up over the next 6-12 months by a statistically significant amount, their GDP drops, the GBP drop today will probably extend some over the next two years, housing prices in the UK will drop, and the middle and lower class people who were most of those voting to leave will suffer significant setbacks financially.
Get a couple other countries on board and the "great recession" from the banks would likely seem like it was just another day for most people. From the point of view of "you want to be able to retire and avoid a ****ty economy", the whole "get rid of globalism" movement is the antithesis of progress.
Of course, an understanding of macro-economics doesn't fit on a bumper sticker, so most people don't bother trying to grasp how much it has benefited them overall when "well, Joe lost his job because company x moved the factory he worked at elsewhere" is so much easier to relate to than the actual total impact of free trade agreements.
