Much like the so-called 'liberal metropolitan elite' who are accused of running things in Westminster, Capitol Hill is suffering from its own image problem.
So while Donald Trump is happy to boast about his wealth ("I'm not using the lobbyists, I'm not using the donors"), the other candidates for US president have spent most of their time downplaying theirs.

But here's how much the candidates who have officially declared are estimated to be worth:
According to the 2014 Global Wealth Report, the average net worth of a US citizen is $348,000 - although that doesn't take into account huge disparities in wealth in the country. The US is home to more ultra-high net worth ($50m-$100m) individuals than any other nation (see page 27).
