Lot of people are telling negative sides career as a physicist, But it physics really in such a bad position? I had a wish to research on high energy physics(particle) . Now i am undergraduate student student of physics major. Should i change field at graduate study? or take risk? If i change field which should be good for usa or canada? But if you are optimistic about physics then say... I don't need much much money. Just own home own car and a smooth life..
