I believe OP is saying that while QoL is great in the Netherlands, it has an upper bound. I suppose that he has access to resources that could provide an ever higher QoL in other countries. For example, in the USA, QoL can be good if you're a millionaire and gets better as you acquire more resources.
Unfortunately, there's no QoL lower bound in the USA, either.
