Basic living costs, yes. But not electronics, video games, streaming services and other things like that.
I will give you a simple example of what I mean. BLC means bills and food, stuff you absolutely need.
Poland - 1250 EUR average income - 750 EUR basic living costs (60%) - 500 EUR left
Germany - 4000 EUR average income - 2400 EUR basic living costs (60%) - 1600 EUR left
Who has an easier time buying a graphics card that costs 1000 EUR or more (same price in both countries)?
New video games cost about 70 EUR over here, which is completely insane.
