We do not have true capitalism in the UK, in fact it is much more akin to communism. The reason for this, is that money itself is a monopoly, controlled by the private banking sector, which has managed to capture the UK government. The root cause of the ridiculous price of houses is that money can be printed at a whim, out of thin air and not associated with real economic activity, by the private banking sector. Just look at how much money has been printed by the Bank of England in recent years. They literally have their own magic money tree where they can print money at will (or create electronic money in a database), which gets transferred to the major UK banks, for them to make loans, the most important of which are mortgages, because these can be collateralised on the property itself, so are the safest loans for them to make. The money printing causes the eye-watering pump in house prices which we are seeing, and prices become totally detached from economic realities of what "normal" essential workers can manage to earn, i.e. what people working outside the financial sector can earn. People working in the financial sector contribute no real value to society, they are just parasitic on the people doing the real work.
If real workers don't like this, they should call for the UK to return to a "hard" money system, where money is "hard" to produce and cannot be printed out of thin air by the financial controllers (i.e. central bankers at the Bank of England). This means backing Sterling by either gold, or better in my opinion, by Bitcoin. This would mean an end to the financial sector's secret weapon of infinite money printing, and the real economy would see its real value, and people doing real work would be rewarded properly, and would be able to afford houses. This would also mean a return to true capitalism, where real work generating real value would generate enough money for people to buy a house, and we would no longer have the phoney capitalism we have now (more like state communism with central credit controlled by the Bank of England).
The more workers understand this, the better, so spread the word.
