Why are Brits so considerate, caring and so different from what they were known pre ww2?

"I am a legal immigrant. A major IT consultancy literally headhunted me and brought me to the UK when I was 41 years old. Apparently, my skills were quite rare in the UK. Ever since I came here, I have felt nothing but love, respect, and great support for me and my family, including my two little children.

Before coming to the UK/EU, I had worked on three different continents, but I have never felt such comfort and genuine acceptance of my South Asian ethnicity anywhere else. So, my question is—why are you folks so caring and willing to go the extra mile to ensure that newcomers are well taken care of?"
