Gold ceased to underpin currencies ages ago. Most are Fiat, ie they are not backed by any commodity but rather on future earnings, and are purely based on trust. A £`1 coin is acceptable in exchange for goods or services solely because both parties trust it to be worth £1.
Yes, it's odd how many people don't realise this. It's money 101, but 'oddly', they never teach it in schools or talk about it to the public. Isn't something like about 3% of all 'money' actually what we would recognise as tangible money, but the rest is just theoretical?
It makes it even more outrageous when you think that banks clamp down so harshly on people who can't 'repay' them, when what they 'lent' just came out of thin air in the first place. You 'borrow' £200,000 from them and it's your act of borrowing that 'authorises' them to create that 'money' out of nowhere - but then you're in hock to them for 25 or more years to 'repay' it. You're actually doing them a colossal favour, but they always treat it as the exact opposite.
If anybody hasn't come across it before, I'd heartily recommend looking up 'Money As Debt' and checking that out.
Things like property 'values' are all part of it as well. Everybody loves the idea of how much their house is 'worth' - and constantly rising; but the only real winners are those who inherit, move from a very expensive to a much cheaper area and, of course (as always), the bankers.
If there were a sea change and the 'average' family house were now worth £50K, people would be beside themselves at how much they had 'lost'. Obviously, there would be one or two generations still with the current-value mortgages who would really suffer, but after that, once it became commonly understood that your average house was 'only' worth £50K, BUT that meant you could get yourself a modest starter-home for £25K, upgrade to a 5-bed detached for £75K or an actual mansion for £100K - everybody apart from the money-lenders would be far better off overall.
The thing that always makes me stop and think is when you look at the world of billionaires. Surely the one overall advantage of being a billionaire is that you can have absolutely anything that you want and never have to think about money ever again; but most of them seem to spend their every waking moment agonising about money - and how to make the next billion - far more than anybody else apart from the very poor who are forced to live hand to mouth.
Money is just a tool, like a screwdriver, washing machine or car. Life is much easier if you have one, and you might find it even easier and more convenient if you have a few of them; but if somebody asked you if you wanted or needed 500,000 screwdrivers or 800 washing machines for your own personal use (not allowed to sell them!), you'd look at them like they'd gone absolutely insane.
