It is. of course, much more complicated than that. Not everything is the fault of Brexit. Hell, even Brexit wasn't the fault of Brexit. It was just political incompetence, pure and simple. No problem having a vote on it, but an enormously serious political and economic change with inevitable decades-long economic consequences should never have been decided on the basis of a simple majority. Even the PL aren't stupid enough to do that.
They may have thought they were going to win, but for God's sake they should have taken it more seriously. I mean, think of the children .... it was always going to be extraordinarily destabilising. So people just have to suck it up and wait for the economic consequences to settle sometime in the next two decades. Resolve the Brexit mess? As you say: hard work and hard decisions.
