Debate on money spent on education of girl is a investment for future

Answer 1

Yes and No!! Depends what you mean by ''Education''

Girls should be taught a standard of Maths and English during 7th-11th grade. This is good because they can educate their children during motherhood, plus...Not be illiterate. 
As for women starting careers. I wouldn't recommend to most, but I do believe they are all free to start one, just like anyone else.

Girls education is equally important as that of boys education. It is necessary for the development of a country since a country doesn't constitute of boys. A society needs equal balance between girls and boys education and that can be only done when both are educated.

There are certain places in our country where girls are not educated thinking that it will go waste. People only focus on boys education because they think girls will get married and go to their husband's house, then what is the need for it. But by educating a girl they can actually educate two families.

But they are not aware of the fact of educating a girl. Educating a girl means development of country, share of burden over families, social awareness, knowledge of their rights and so on. So we should educate the girl child.
