Nope - nothing objective about it. I moved to the US from a European country with a supposedly higher standard of living. I worked longer hours here, experienced workplace bullying, and a whole host of things that would be illegal in my original country.

However I also experienced more freedom and diversity and was able to find a much more heterogenous community, as well as do things that were simply not allowed in my home country.

My life is much richer here and so the US is much nicer for me to live in.
