I basically agree with him. I do on most issues concerning the EU. Here in Germany the mood is pretty bleak right now. I can only answer for my own country, but think we Europeans often share similar problems.Today is our national holiday, so not the best time to talk about everything that is bad about my country, lol, but since you asked:
Germany has some major problems, most of which are interrelated. As you know, we have a serious demographic problem. Too many old people, not enough children (I also don't share your optimism that this can easily be stopped or turned around - if you know the secret solution, sell it to the Chinese government as they are having the same issue and so far have not been able to solve this). So politics and economics are dominated by older people with an older people mindset. On top of that Germany is structurally conservative to begin with. The country is like a big heavy oiltanker. When it is on course it can venture through storms untathered (which is why we suffered less than others during the 2008 financial crises) but when it drifts off-course it takes some very hard work and/or a major crises to get it back on track. Stable, but not very agile. This is partly due to our history, partly due to demographics and partly because usually our way of doing things is the result of long negotiations and a delicate balance between different social interests. It is hard to change anything without upsetting a lot of people.
We should have totally reformed our economy decades ago, from fossil fuels and combustion engines to renewables and electric vehicles (plus mayor investments in infrastructure). There was a time in the late 90s to early 00s when this would have been feasable and it looked like we might take that road. But then we didn't and have dragged our feet ever since. We clinged on to producing combustion engine cars like Jack in Titanic to the floating door (and we all know what happened to him). China has long since overtaken us in those technologies. It was and is deplorable. Right now our physical infrastructure is falling apart (sometimes literally and quite spectacularly as was recently the case with a collapsing bridge in Dresden). Our roads and railway network needs investment, as does the education and health system...and housing! This is the result of decades of fiscal conservatism (the Merkel administration added a rule to the constitution that forbids deficit spending) and general structural conservatism. Most businesses know this and urge the government to invest...and to set some clear climate protection rules so that they know what they are dealing with!
As an export driven economy we need the Chinese market but also fear Chinese competition. I personally haven't given up on international free trade as an ideal but also come from a culture of ordo-liberalism. So, ideally everybody would "play by the rules" and we profit from a rules-based international market, but if it is necessary to stabilize and salvage Europe, bring on the protectionism and fortification, I guess. *sigh*
You probably already know most of this and probably also know that I am a somewhat naive and romantic adherent of the ideal of the United States of Europe. So, yes, strengthen the internal market and ease internal trade - after all our biggest export market is usually each other. Cut red tape whereever it doesn't mean significant cuts in environmental protection or workers' or consumers' rights. I am also strongly in favor of a much more closely coordinated foreign and defense policy, including joint European defense forces. And a new and fair capacity based system for the distribution of refugees, while we're at it (either take people or pay others to take them for you, basically like emissions certificats, would be a suggestion). Naturally not everybody will want to be part of that kind of close union. That's where the old concept of a "two speeds Europe" comes into play - something like type A and type B membership.
So, yeah. We'll need some major efforts and radical changes in the near future, many of which require long term vision, large investments and the supression of a lot of egos. Is it possible? Technically, yes. Do I think it will actually happen? I am not holding my breath.
