Sweden had to raise its retirement age from 60 to 69 to fund the welfare for the migrants.  Previously, they had a 5 year surplus in their state pension fund, meaning they could have lowered the retirement age to 55.  That is a 14 year loss in their state pension fund, solely due to migrants coming to the country so they can get welfare.
