The reason bankers are paid 100x more than other people is that it takes as massive amount of skill to lose massive amounts of money. RBS, for example, have lost almost the exact amount they were bailed out with, and still insist they have to pay top dollar to get the best staff. Which tells me they would've lost more if it hadn't been for the useless lot they employ currently. Let 'em go under.
The current economic model, which some call neoliberalism, is a huge Ponzi scheme, in that all money rises to the top from those underneath who end up subsidising them. It requires those at the bottom to borrow just to get by. It is doomed to fail, it always has in the past.
Currently stocks and shares are at an all time high, and house prices are rising faster and faster. One reason is that banks and corporations can borrow money for almost nothing. Mostly what banks have been doing the last few years is lending it back to governments at 2% (ish) interest.
Because here in the UK we have a debt based austerity economy those who spend the most as a percentage of their income, the poor, have less coming in. So they spend less, thus shrinking the local economy. So many have had to turn to pay day lenders who charge high rates of interest, meaning, in reality, their income shrinks even more.
What makes things worse, and something that must change, is the way banks create money at the stroke of a keyboard. When you get a loan they access your account details, type the amount you're borrowing and announce that 'the money' is in your account. This non-existent money makes up much of what is out there, about 97% in fact. Money creation should only be done by the central bank, though that should be looked at due to the amount of QE that's going on. QE is going to cost in the long run as it will devalue the currency.
In short, the system is fucked and it's going to crash, and there's nothing we, the little people, can do about it. All we can do is insure against it by using our devalued pound to buy gold and silver (and Bitcoin), because gold and silver prices are being held artificially low to keep the dollar high. Why China isn't calling in all their dollar debt is due to them being able to snap up gold at a discount. As soon as they call in their debt, gold will rocket, the dollar will tank. As will the pound.
