Think about it. Its not about education. How do you know who is a right or wrong person? There are millions of educated people doing wrong things and tens of millions uneducated people doing right thing. A country can't peogress without human equality. If the control was given to only 10% educated people, this country would have becmome a much messier state than Pakistan. India didn't have common language, religion. It was plagued by castism, poverty, illiteracy. Without human equality country wouldn't have progressed. So, adult franchise was the RIGHT decision. Political leaders reflect the society they represent. Social changes requires much longer time than you think. So, the progress is always slow. When people talk about Japan, they forget the state of India in 1947. It is easier to construct new bridges and buildings but bridge the gap between different communities it takes much longer.
