Reasons why 21st century won't be that bad?

[VaeVictis]

Technologically and scientifically speaking, we have and continue to make great strides. However, there are major issues still facing humanity before we can pat ourselves on the back for being superior to our ancestors. Human trafficking comes to mind, which is a major problem the world over. The distribution of wealth continues to become more and more skewed as poorer countries are still being deprived of their own natural resources to feed more wealthy counties.
In many countries, women continue to be treated as garbage. Even in wealthy countries, there is still much work to be done. Even more so for non-binary genders.
Slavery may have been abolished in it's more primitive sense in western communities, but it's still alive and well in different forms in these same countries that pride themselves on being 'above' others.
And still slavery exists in the world:link

And let's not forget that our environment also needs our help.
Have we come a long way? Yes. Are we headed into a utopian society any time soon? Not without exhaustive, pointed efforts to confront these issues.

We have much work to do, and it's best not be get complacent.
