&gt; Doesn&#x27;t the financial sector employ pure maths PhDs and pay them extremely well?<p>There are a few big names who make a lot of money, but on average someone with a PhD and x years of experience will be paid less than someone with a masters and x+3 years of experience, AIUI.<p>&gt; And you can apply an art history PhD in museums, galleries, national collections, etc etc.<p>Sure, there are a few options, but how many of those jobs are there per PhD?
