I truly wish I was relevant enough to you to hear it sometime, Most of us over 50 can relate to WW2, and the horrors it caused to citizens, but this kind of invaluable first hand info is being lost on successive generations. We (Canada) used internment camps, with forced labour, in both wars here and refused entry to Jews during WW2. We haven't learned, but we do have to insure, proper vetting is not overlooked by compassion.
Philosophically, I'm generally against migration, in todays world, even domestically, but recognize the necessity of 'people trading' just like the trade of goods, and more importantly, I support the freedom to do so, within the law. Refugees are a distinct difference from immigrants, but both contributed to Canadas largest population jump despite the drop in birth rate, in the last few years, so there's some math to do.
Kudos to your familys' success, you come from strong stock.
