Is it a good time to work for a Hedge Fund/Investment Bank?

I have 2 degrees in International Finance and Accounting from a Top school in the West. I am 28 years old and I have 3 years of work experience as an Accountant, I have taken the CPA exam but I am not licensed because i need a Masters degree in my State of residence. I am thinking of going to school to get my MBA in 2 years and I want to venture into working for a Hedge Fund or an Investment Bank as an yst. Can anyone tell me if this is going to be a good career change? Is there a future in working for a Hedge Fund or even an Investment Bank with all our current economic woes?
