Why exactly will they be harder to solve? This is what I'm struggling to understand.
We have a first past the post system. France have a presidential system (one in which last elections people completely rejected the status quo and also swept his very new party into power in the parliament). Germany have a PR system, with a culture of coalitions and compromise. Belgium have an absolute joke of a system where their country basically seems to have no functioning government whatsoever. Etc etc.
We had a chance to change the system in 2011. The Lib Dems first of all went for a compromise on a system that was pretty crappy anyway and then somehow didn't get the Tories to stay neutral on the matter. And the people voted against AV, with a 42% turnout. Where was the EU in all of this? Did they tell us to stay FPTP? That AV was brick? That we couldn't have a referendum? That we needed to go to PR? Nope, the EU didn't get involved at all because it is absolutely none of their business.
What has von der Layden said?
Also I know you're being flippant but you must know that this comment is just untrue? At the very least by dint of the fact that they come from a pool of dozens of countries with about 500 million people, as opposed to 1 (4) countries with 65 million? I've just done the most cursory of searches for the last 5 European Commission presidents (excluding the interim one) and they come from 4 different countries and studied at 5 different universities across 5 different countries. Though unsusprisingly most have done law or economics. Contrast to this:

Nobody is forcing our people to continue to vote or continue to elevate people who did PPE at Oxford or to lick the boots of those who went to Eton/Harrow/Winchester and yet we continue to.
I'm 400% sure that our politicians will continue to blame the EU afterwards. If we leave on a no deal and our economy responds accordingly, I reckon that will be a good few decades worth
Out of interest, what changes do you think you want to make to British society and the way we're run that you feel we can't make currently because of the EU?
