Because young Indians are too stupid to understand any text in the Sanskrit language (even if they knew Sanskrit). The only thing that they can understand is how to make money and …. All finer qualities like respect, tolerance, humility, etc. are lost on them. So, even if they were to learn Sanskrit, they would not get anything. So, it is good that young Indians leave "stupid" Sanskrit language alone, because in reality, learning Sanskrit will make YOU look stupid.
