Judging from the dark blue line, Danes appear to be net tax contributors from their later 20s to their later 60s. They get very expensive in terms of tax consumption in their 80s because, I’m guessing, they less often have family taking care of them. People of Middle Eastern, North African, Pakistani, and Turkish descent (not just immigrants) come closest to paying more in taxes than they consume in services around age 42, but are never on average net contributors.
