Lol, my perception of Africans is that they're lazy. I don't like to generalize, but I think it's (lazinees, unemployment etc.) more allowed and accepted in African and Middle Eastern cultures.
Why do you think people in the Western world and Japan are more developed? Discipline has been programmed into their minds.
I was born and raised in the USSR. If you was unemployed in the USSR you could go to jail. It is big contrast between USSR on one side and Africa or Middle East on the other.
Not IQ, but discipline is the magic word!
If you label people with words with socio-emotional context you will fail to understand how world really works. Word "Lazy" have a bad connotation, but it shouldn't. In nature there is no bad things or good things. They are just are different things. All things can be beneficial under right circumstances. For example "lazy", or rather energy conserving trait, can be a beneficial for individual or a group of people in certain environments. If you in Africa and work like workaholic in a middle of the day in +40C it can be fatal. Your workaholic genes are finished and not carried over to next generation.
Same thing in times of food scarcity. Running around like crazy looking for food that is not there will exhaust you and kill, together with your kids. Sitting around, conserving energy, often is more beneficial and lets you survive till next rain, or till next successful hunting. This is typical for Prairie Indians or Australia Aboriginies. Pure hunter-gatherers.
Most of Europeans will label them lazy, as per their mind set of Western hard working/production oriented philosophy of life.
Yes, it's true they are not adopted to western way of life. They are excellently adopted to their hunter-gatherer ways, and survived in local environments for tens of thousands of years. Now this their big success.
Now, before you start comparing others to western, as you put "developed" (most likely meaning "superior") ways of life, keep in mind that we are only "developed" for last couple of hundreds of years. It is a damn short time to decide if the new ways (superior ways) are good, meaning beneficial for our groups. If we survive ten of thousands of years, preferably a million, in this developed stage, then you can claim that.
Unfortunately, we got so developed that population of western countries are falling down in numbers. Japan from 120 million people in 80s, is down to 110 or 105 now. Europe is following this trend too. With this speed our developed civilization will vanish in couple of hundred of years.
Now tell me, is being developed a good thing or a bad one for our species?
As hunter-gatherers we existed for millions of years, as agriculturalists for 10 thousand, as technological society for couple of hundreds (and maybe near the end?). How do we measure success and superiority?
Keep in mind that life on earth is always about next generation. It's not about your happiness, or your culture, or language. It's about your genes, and your genes being carried over to next generation. If this principle is not fulfilled, your line is dead. If group fails, then your species can be wiped out too from this planet.
Life on earth is about next generation. Judging by this definition of life on earth and history of humans, we can conclude that so far we were the most successful when we were hunter-gatherers. We had more generations than agriculturalists and "developed" westerners combined.
