<p>Yes, some physics majors do go into finance. But others go into other technical or engineering fields (though more so the ones where professional licensing requiring an ABET accredited engineering program is less of an issue, like CS and some areas of EE, rather than something like civil engineering where a PE license is pretty much mandatory).</p>
<p>Similarly, finance is one (though not the only) thing that applied math and statistics are specifically applied to.</p>
<p>In any case, the additional job and career options in finance and the like help make the job and career outlook much better for physics, (applied) math, and statistics majors than it is for biology and chemistry majors. But it is not the only thing that makes it better – the other thing that is likely making the biology and chemistry job dismal is the overabundance of failed pre-meds flooding the market.</p>
