The revolutionary government will allow the bank of England rate to rise by up to 0.5% per month for the first year if market conditions require such an increase. Artificially low interest rates for the banks are a major cause of economic bubbles. Quantitive easing is another. Payday loan for you 4000 % or more, loan to a bank 1% or less. The Revolutionary government policy of 6% for banks and an absolute maximum for you of 26% is, apparently, truely revolutionary. The maximum rate for paying of you credit card will be 1% per month, around 13%. It will be the lenders job to check your ability to repay any loan, and this will be retrospective. If they should have reasonably known that you would be unable to pay the loan, when they gave it to you, and you have made reasonable efforts to pay, then the amount you owe will be fixed as though the rate was always 13%, the rest will be written off by the loan company.
So what is the Economic theory?
Wholesale Interest rates should lead to a balance of savings and loans, and stability of the currency. Usuary should be illegal. The solution to unemployment in the longer term is to be found by providing stable conditions for industry, reasonable levels of taxation on industry and workers, savings to be encouraged and loans to be directed to productive use  and not to speculation.
