Well, there are two connections here that for some highly educated forum participants are cheap pub clichés and cannot be correct at all due to highly scientific sovereign argumentation:
1) Migration leads to increased demand for living space. This increased demand and the resulting pressure on the real estate market lead to higher prices and scarcer building land.
2) If the ECB prints money relentlessly for years, keeps zero interest rates, and buys billions of southern states' government bonds "whatever it takes," then that is eventually a reason for higher inflation rates.
Both are profoundly wrong from a scientific perspective :)
Regarding 2) I somehow feel addressed. I never said anything about 1). Let's set science aside, which is just a method and not a thing. Let's try another method, logic:
IF the current inflation is caused by the ECB's "money printing," zero interest rate policy, and government bond purchases, then logically and necessarily it means that it is NOT caused by supply chain problems and the Ukraine war along with sanctions. THEN two questions:
a) What do supply chain difficulties and war with sanction policies actually lead to on the price front?
b) Why do countries that do not have the ECB as their central bank see the same inflation?
