If you're set to inherit properties/money from your parents or you're ok with being a renter for life at the mercy of your landlord then any salary in Europe is fine.
If you have to buy a property on your own where you could raise a family in then salaries are far from fine.
Anytime I her someone in Western Europe say salaries are fine and shrug it off, usually it's because they will receive an inheritance or significant financial assistance from parents when the time comes to buy a house so they never feel underpaid.
