The fact that problems are solved using calculators and computers doesn't make math less necessary. It is even MORE necessary - how do you think all of this technology was designed and built? If you don't think that math is the answer to that question then you should do a little further checking!
I think that math isn't emphasized in modern households because our society is becoming complacent. The attitude seems to be "Okay honey, I understand you're not good at math because when I was a kid I wasn't good at math either." It's too hard, so emphasis is put elsewhere. As an example of how deep this problem goes, in some states if a prospective teacher doesn't pass the math portion of the teacher certification exam, then it is waived! And then we wonder why there is a crisis in obtaining qualified math teachers!
Also, the image of the "math nerd" has really been promoted by our society. In previous generations people who pursued and excelled in math were highly respected. Now they are just considered not cool.
