So there's an opportunity for some investors to win big but most of them will lose. And even the ones that win will likely lose out on their next gamble. Such is the way of unstable markets.
Does it? My gut feel says 50/50
My point was that calling uncertain times uninvestable is stupid. It is a different climate and for a certain type of investor it is a gold mine.
This is the opposite of what history shows. Markets have grown on average. Buy a varied assortment of assets, an index of British assets, you’ll do fine. Just don’t expect good quarters in the short term. You’ll be up a lot in 10 or 20 years.
Buying into a risky market right before a down turn will only increase the time for you to see a return on your investment. Meanwhile you could have been making a "steady" income in less uncertain markets. Or even invested in the world market as a whole.

I doubt that most British people in finance were Brexiters, but rather Bremainers. And so it's not the job that tainted them, but rather the job they chose suited their personal traits.
In other words there might be some chance of immediate and long-term benefits in "hard" Brexit for some, but an enormous short and long term damage for the rest of the population.
