<p>Like most science degrees physicists are paid well and there is quite a bit of job growth predicted (14% in 10 years). It is competitive though, its not a huge segment. Also you will need a graduate degree to be competitive. So yes if you are looking for something you can go right into the marketplace after 4 this might not be the best choice. </p>
<p>Mathmatics I can understand but im not sure about econ. Best job opportunities will be in tech jobs like IT and anything health care.</p>
