Female's salaries low than male?(question1)

In the past,female are always minority than male.No matter jobs,salaries or power, and so on,
male had advantage than female.Why is it that females are immersed in poverty easier than males? Statistics propose that there is a basis for their lives difficulty. According to the number of UN, about twelve to thirteen billion populations are immersed in poverty in the world, and nearly seventy percent populations are females. Although female or male poverty rate was still rising from 1996 to 2000, the poverty rate of females is higher than males. I list three points about the problems:

The first is historical reason because old people value male and depreciate female.They thought female should took care in husband and children,they shouldn't go out worked. If they went out worked,somebody said the woman didn't have virtue in the past.

The second is political reason.I think governments are important supporters becauce governments should help female search works and protect their lights and rise their salaries;don't should ignore their existence and discriminate against female.

The third is culture reason.India and backward countries have the problem because their culture is already deeply root,female's rank low than male,so salaries are more low than female or
even who didn't have salaries became slaves.

The problem is not easily solve,if the problem had solved,it couldn't just a trouble thing.
If everybody want to solve the problem,we should change our thinking.
Why do we have discriminate against female?Everybody is ''Man'',we should't differentiate male and female.God create Eve just company Adam so male and female are same,they can do any works not only male but female.
