I was going to ever so clever and point out the difference in price over the last 50 years and how prices have dropped in modern times due to farmers becoming more 'efficient' and cramming many more birds per acre .... but a strange thing happened

We kept "true" free range chicken back in the early fifties at a rate of about 200 hens to a 7 acre field, and I remember that we used to sell them to the egg packing station for 2/6d a dozen. This was at a time when the average labourers wage was about £10 a week, so our average labourer could afford to buy 80 dozen eggs if he bought nothing else.
I just looked up the minimum UK wage and found that it is £5.73 and hour or £229.20 for a 40 hour week.
T***o's free range eggs are £2.92 a dozen which means our average man can now buy just under 78.5 dozen eggs.
I realise that I'm not really comparing like with like, our eggs were sold wholesale and I'm comparing retail, but even so how amazing is that, the price of free range eggs is almost the same over a 55 year span.
