You’re thinking of happiness as a binary, but the surveys you list describe it as a scale. Most people in Bangladesh don’t meet many of the criteria in OP’s list, particularly income security. (They can feed themselves but that’s about it, and that’s not guaranteed.) So why do they rate themselves a 4.5 out of 10 on global surveys instead of 0? Because family and faith is an important source of happiness. Having kids and being able to feed them (which is a condition short of “income security” as postulated by OP, and is one that even most people in Bangladesh achieve) and participating in your religious community produces a certain baseline level of happiness. Those people would be happier if they also had income security and a fulfilling job. I agree with you on that. But their families and faith are a main source of what happiness they do have. Omitting those things from the list therefore overlooks a huge swath of the human condition.
