IS BIOTECH GOOD THING OR NOT?

I just want to know whether this future job that my sister will take which suitable for her college course is a good thing and if it has a lot of benefits you get when you'll get this job. I want to help her since the course she take in our country isn't common. Additionally, my sister wants me to ask for her in this sub.. thanks in advance for the advice.... please don't hate me because I'm also not familliar to this job and the course she take..
