You can enter plenty of fields. The most common ones are arguably the Civil Service, Law, Politics, Teaching, Information Management, IT.
In all honesty, no degree guarantees you a job, bar Medicine. So it's better to get the government to pay for you to study something you enjoy, rather than something you 'think' will have better job prospects.
What areas/salaries you will be earning will also depend on your A-level results, university and most importantly degree classification, you NEED a 2:i. Everyone thinks financial services are 100% Maths, Econ, BSc grads, but they aren't. They recruit from a variety of universities and from a variety of degree disciplines. Similar to Law, you will find 50% are law grads, and 50% will be doing conversion degrees. Options are open with a History degree
to be honest, look at financial services right now, they're doing pretty crap, and you don't really want to do teaching with an Economics degree, because that would, well, be a waste of potential earnings, whereas with History, it can act as a safe fall back option
