Depends where you want to work. Though Investment bankers are getting flack for the mess they have created, you can be sure they will come up with something new to make money.

People will always need money, so you can be sure investment banking is going to be around for a long time to come.

They get paid well too, you can always diversify into Fund Management or other areas of finance, if you see the situation is not that good in 2 years time.

Go for it!

right now would be a very bad time, when investors’ confidence is very low. perhaps in two years hence, the conditions may change – and the investment climate be bright again.
