When you examine English history they'll soon learn that they arose to the lofty heights they have only because of immigration and immigration alone.
They imported tens of thousands of Belgian weavers to England to capitalize on the abondance of wool they produced and this gave them a lot of riches since everyone in Europe started buying from them instead of Belgium.
They used to get their ships built in Baltic ports until they imported Baltic ship builders to the UK and built their own ships and a navy that had more ships than the rest of the world combined, they imported German miners and metal workers to start their metal working industry.
Imported Italian and dutch fisherman to develope their fisheries into the best in the world.
The UK is a country of immigrants with it's strength being primarily immigrants, stop being racist to pajeets, nafris, balkaners, and Slavs then, they're your true strength. You must value you them above an Englishman.
