Hey ho! That ending was unnecessarily rude. I don't think he planned his post as a personal attack on you or your values, so I don't think the hostility is necessary.

For some people it's easier than for others. I work with a ton of people who've migrated to Sweden. I think they find 1 and 2 fairly easy -- not trivial, mind you, but not hard enough that they can't be overcome. The third problem varies from person to person and what stage in life they're at. We have many people who have moved here with kids, and it seems to work out well. So it's certainly not unsurmountable, but yes, not easy either.
