At least post some actual data, geez.

What I think about this? Well, lots of thougts.
But to make it short:

1) Not only Europe. The worst off are east Asians. Apparently this is more or less a global problem, but it appears in different cultures little bit differently. East Asians are being extreme example, as in any other fields of statistics. Africans and MENA people, on the other hand, are being more "conservative", but still in the trend.

2) In general, this shouldn't be a huge problem. Less people shouldn't mean shit. The problem is our economic model of our industrial society. All the rules, that we took for granted, that we build since industrial revolution and implemented them en mass after WWII - they need to be rethink. It's about adaptation. But our globalistic society does not want to adapt. Why? Because back to demography - we are in gerontocracy model. We build a society that benefits just one generation of people. And instead of moving forward and starting to benefit also another generation, we just made it stuck just to one group of people, forever, until they die off. Boomers will bring this society to collapse, they need to drain the society. Until the very end.
Now, the adaptiation strategy doesn't work and instead we, the millenials and zoomers and younger, we need to implement the resilience strategy.

3) Last but not least - as we are on /pol/, you are probably trying to raise up worries about race and nationality and culture and other bullshit. Well, I have good news for you, you don't need to worry.
No immigrants will want to come to economically dying countries.
There are more serious threats for culture identities. And the most serious is alienation of younger generations. You want to make your nation to lose the culture? Well then the best strategy is - alienate the youngs. And that is exactly what is happening.
