Yes but not for long.
As (generally climate denying) people love to point out, wind and solar is erratic power generation. For this reason you need triple capacity Vs requirements.
This means that for a huge amount of time you’ll have excess energy, once we start to be predominantly renewables, battery storage is expensive. One of the solutions is to create hydrogen, also pumped hydrogen, etc.
1950s, the time of plenty… if you ignore the rationing you mean? Life expectancy of 69 (12 years less). Infant mortality was almost 10 times higher, 30 infants died per 1,000 births vs 3.25 per 1,000.
Healthcare has grown from 3.5% gdp to 9%, more stuff gets treated.
There are double owner occupier housing now. 1953 was about 30%. 1956 is when protected rents ended and rents started to increase massively.
Defined pensions were taxed to death by Brown. They do still exist though (I have one, along with a SIPP). More people contribute to pensions than ever before and the age people stop work is starting to decline.
