There were millions of deceased and millions others murdered in the holocaust, so overpopulation wasn’t an issue after world war 2. The displaced in Germany were Germans, so culture wasn’t an issue. Yet, refugees were discriminated against with pretty much the same rhetoric that is currently used against Ukrainians and Syrians.
I live in Germany and I have a lot of problems:
we already have water shortages due to climate change
the heat waves are a new phenomenon and they’re unbearable because no one has an A/C and due to the housing crisis I can’t buy my own home where it would be worth to shell out thousands to install one
the lack of digitalization in this country is crazy, I have to check my mailbox every day and many government tasks are still done by mail or fucking fax machine
the already mentioned housing crisis makes it impossible to find affordable housing and if you find it you’re trapped there forever, I can’t even think of having kids because I know I won’t be able to find a 3 room flat
public transportation in my place is already top notch for Germany and it still sucks, they had to reduce busses and metro because they can’t find enough drivers and they’re chronically underfunded. As a consequence you often have to go by car and be stuck in ridiculous traffic jams
the pension system will collapse when all the boomers retire, there won’t be enough people to pay for their retirement, politicians know this but are completely ignoring it
our infrastructure is rotting away and because of self-mandated austerity the state is incapable of making investments into our schools, roads, railways, hell even electricity grids
for a developed country our internet speed is ridiculous because we’re still mostly relying on copper cables instead of fiber
Our current governing parties are eroding our democracy through pushing mass surveillance, silencing the press and violently suppressing protests against climate change, genocide, etc. s.t. we don’t even need actual fascist parties to slide into a state of fascism
Asylum seekers and regular work migrants are not the problem, in a more pragmatic society they would be part of the solution. I have no negative impact in my daily live from some poor fuckers who are fleeing from warzones and crazy dictatorships but all of the above are affecting me constantly. Btw I don’t understand your remark about caucasians, can you explain what you mean with that?
