That's microscopic change
In macroscopic view, they are unchanged.
Then, your two argument may cancel each other
Less birth rate = less competitors
Delay retirement doesn't do anything to my point. I meant, death and getting married.
less birth rate = less options
no matter what competitors are increasing but at a decreasing rate
death? people have a longer life too and many old, rich men still play active at their age
getting married? huh? only if people can keep promise otherwise one can have few partners at the same time XD
delay in retirement is my point and i was asking to take it into consideration that's all!
