Not only that, we also spent most of our working lives paying for the loans to compensate slave owners when their slaves were liberated. Particularly annoying for DH being the descendent of slaves to be paying the loan to compensate the people who exploited and abused them. The loans weren't paid off until 2015 so plenty of younger people also paid but not for 50 years
This is a nice fantasy but not reality in any meaningful sense.
The 1835 loan was £15 million and the interest paid was 3% per year until such time as the government chose to repay the £15 million. In general it didn't make sense to do so, as the government would need to pay more to repay it. The 1835 loan itself was refinanced in 1957 so no longer existed at that point and indeed holders of 1835 stock had the opportunity to redeem or take new loans at that point
The 1957 perpetual loan which consisted of some money held since 1835, in 2015 because interest rates were so low was repaid by the government and refinanced.
It's not really accurate or meaningful to describe the slavery reparations as being paid in 2015 since the original loan no longer existed and since the loan was never designed to be repaid - in the 1980s, for example, the value of the 1957 paper would have been far below the 1957 value of £218.4m (made up of multiple earlier loans including the 1855). Even by the late 60s the bank rate was double the 4% of the 1957.
Hence since inflation averaged 5.5% between 1957 and 2015, it follows that the loan cost nothing at all - we paid less interest (4%) then the money cost.
The loan was paid by the generations between 1835 and 1914 when inflation was zero. Interest was real interest and with no inflation, then by 1914 that would have been £35.5 million in REAL money i.e. more than double the original principal.
WW1 cut the value of the loan in half, and by 1957 it was worth less than half again.
So essentially the loan was paid from 1835 to 1914 and from that time inflation ravaged it so that we were paying far less in interest than we were saving in the reduced value of the loan.
So it really isn't accurate to say we were paying the slaveholders loan in 2015, firstly because it no longer existed in 1957, and secondly because perpetual loans had for decades effectively become a profit centre in the government accounts (if you have £1 billion face value debt and next year it's worth £900 million real and you pay £50 million interests you made £50m profit)
At the point it stopped being profitable due to low interest, we refinanced in timed debts which are refinanced over shorter periods. Therefore in that sense the debt still exists and will never go away ever ever till the universe no longer exists, in as much as it was meaningful to say we were paying until 2015.
But in any case let's be clear that the descendents of Norman invaders still own vastly more of the country than they should by chance, 1000 years on, which is why people complaining about the Queen are wrong - it really is her land, unless you want to confiscate and redistribute all private property....
