Every single person should be given every opportunity as every other, but we shouldn't continue this state-forced results based on people's personal politics about how they believe the world works.
Why do we have issues with providing everyone with healthcare, clean water, and safety... We're bombing seven countries, funding jihadists in Syria, creating a surveillance police state. Some US cities have murder rates higher than any country in Africa or the Middle East. We can't provide everyone with housing, and we can't successfully protect our environment. Give me a break. This issue is not about human welfare, dignity or equality. This is about people's personal politics and lawyers finding a way to cash in on laws that may have been well intentioned but since gone out of control.
The social ladder and ranking is also attached to the same incentives. A mans ranking is (mostly) based on his ability to support a family. A womans ranking is (mostly) based on her ability to raise a family. As sad and depressing that is, the message it sends on a cultural level is that no one wants to be near a poor male or infertile female. On the flip side, women are not punished by society for not focusing on maximizing earning potentials, and men aren't punished by society for not focusing self care and longer lifespans.
Going even darker when looking at incentives for earning and lifespans, we can look at the link between low income for men and suicide. About a factor of about 1000% according to some studies when comparing high vs low income. Suicide is also the most common cause of death for men at ages 15-50. The negative impact from unemployment (and low income jobs) effects men more, and a natural conclusion would be that the incentives to avoid it is thus stronger.
So yeah, sure, if you look at the scenario in simple isolation, then you could argue that there is a "greater opposing force".
Does the CEO have the highest IQ in the company? Is the president the most intelligent person in the country?
Then why is it that on average they get paid less than men for the same job? Surely if they are inherently "smarter", they should be dominating the knowledge economy and earning more than men. The fact that they don't points to some greater opposing force that needs addressing.
