Why so many marriages fail in the US

[Anomalocaris]

because marriage as you know it is a institution designed primarily in a more primitive age to perpetuate social hierarchy evolved to handle many communicable diseases for which there is no cure, very high infant mortality, and heavy reliance on greater upper body strength for economic productivity. it is failing now because thanks to the habitual tendency to dictate based on made up reasons that characterizes religions, particularly overreaching expansionist imperial religions such as christianity, it failed at all to evolve with human progress.
