Just so you know, inheritance tax in Germany inly kicks in, if the inheritance is over 500.000 Euros and then it is 20% I believe. So your argument actually falls a tad short here.

I don’t understand your point. I get that the limit is high but it does not make any difference: you lost your parent and you need to pay for the privilege to keep their inheritance. How many money you could or want to tax is irrelevant in my opinion. It is a tax that should be deleted for everyone.

Also the current competition in agriculture only promote the commulation of farms into companies.

Which can be not that bad to me

The farmers who actually need support don’t get it, which further accelerates the industrialisation of farming.

Maybe. But what the subsidies have done until now are only damages: they have not helped the farmers and have not stopped the industrialisation.
I don’t really know what the solution could be but to me the subsidies are not the solution.

Lastly, while the AfD has for some time been saying they want the EU to stay and Germany being part of it, they are now discussing a German Exit. As if that did any good for the UK. It would likely be even worse for Germany

True, but this is a consequence, not the cause.

For example, why do you think that Meloni won last time ? Not because suddently 30% of the Italian population became fascist but because she aknowledged the problems people have and that the left (and the EU) choose to ignore. Remove the causes (read: do what is good for your people) and you remove the ones who want to destroy EU because people would not have a reason do destroy it.
