100%. And this has been repeated generation after generation. Its just that in the past 50 years we have started caring and being kind towards ourselves and it has shown tangible results in the progress of human civilization as a whole.

But some regions/cultures are lagging (but catching up fast) as per my experience living in 5 states across 3 countries spanning two very different continents.

What about before? When and why did we stop caring I wonder.
