I need some course/career help!? Mini rant!

Ok I'm in 5th year and am giving a lot of thought to what I want to do for the rest of my life. I am a bright and competent student aiming for at least 500 points or more depending on what course I choose. Money is a big factor for me but at the same time I want an enjoyable job! I am good at and enjoy English in school.

Lately I have been researching courses and careers a lot and am fairly pissed off at what I am finding! For example, say I bust a gut and study like crazy for the next two years in school. I get enough points for psychology in trinity (565). After 4 years study and min 3 years postgrad study I will more than likely get a job that only pays 35k a year, after many years potentially 50k. All that hard work, getting the top 1% in the leaving cert and paid the same as a plumber or mechanic (no disrespect)! This just doesn't make sense to me! Arts courses seem to lead onto underpaid employment?
Mini rant over, can any one reccomend me any courses that lead on to careers that can potentially pay 80k plus? Not a complete money orientated fool, just would like to provide for a family and have a good lifestyle while doing something I enjoy. Good at English, Business, Biology, Economics, technology.
