I do not believe I could have achieved what I have in the last half-decade if I had stayed in the UK. There is something deeply rooted in the UK's contemporary culture (which I cannot yet fully explain in words) that serves to crush the individual ambitions of the working and middle classes.
One business thing that really strikes me is that people in the UK treat bankruptcy as a moral failing, as if you cheated your investors, and not a strictly financial one, as in, you ran out of cash before achieving product market fit. It seems rooted in an unusually Victorian ethis, which is ironic, because in that era, businesses started and folded all the time.
As an American I realize our culture encourages taking risks and we are remarkably forgiving of failure. In fact, we seem to congratulate people for the fact that they tried in addition to overlooking the failure. I’m not sure if this comes from “the frontier spirit” or if this mindset used to exist throughout the Anglosphere. In any event, I do feel bad for the UK as a whole. It just seems like things keep getting worse and at some point the national mood becomes a self fulfilling cycle.
