Whats your take on Volcker

Hey Guys, I am going to be attending college this fall and I want to pursue a career in high finance. I have several questions and conerns and was hoping you guys could help me out and give me you input. 1. What is the future of finance, specifically S&T, going to be like with regulation such as Dodd-Frank and the Volcker rule? I understand that much of the profit of the big investment banks come from their trading activities, so how will they be affected by the Volcker rule which will, in my understanding, prohibit all prop trading by banks?

2. With trading becoming more computational, algro trading has risen dramatically in terms of volume, is it better to major in computer science/math rather than econ or finance. Majoring in comp sci or math would also allow me to develop skills that could be used in other careers. Majoring in finance/econ would make a 'book'

3. I will also be attending Rutgers University, I know its not a target school but it is ranked high in computer science and math, will I have trouble landing interviews or should I be fine with strong networking. I was able to network my way into an internship this summer at a media company

My main concern is how regulation will effect employment opportunities. Will trading still be strong on the private side (private equity, hedge funds, prop shops)? What do you guys think will happen in terms of regulation to the derivatives market?
