It is good to be aware of the trends but by no means should salary be thought of as a criteria for joining any industry. You should go in for whatever excites you or you are passionate about which is what will take you through all the years of your career. The industry shall have its own cycles and will go up and then come down and then again go up... if you are good at something, and I mean really good, you will find that money shall come irrespective of the trade.
