You say your are a trademan ,So lets Have a look at the amount paid into the system by a 67 year old retiree fitter/trademan in income taxes employers/employees over there working life,
Most would have started serving there apprenticeships aged 15/ 16 , so they would have started work around 1966/67
Anco Who looked after apprenticships back then worked off a full trademans weekly wage set at 8.50 pounds a week
First year apprentice would get 1.70 per week less Prsi stamp was .5 of a pound no matter how much you earned all taken from employees wage
back then,
First year if you were under 16 you got 1.7 per week when you reached 16 you weekly wage fell to 1.3 pound a week all of the Insurance stamp came out of the employees wage back then so 29.4% of your wage went in Insurance stamp,
it went up by 1.70 each year reaching full trademens wage in year five 1971/72 by then you were well into the income tax net ,
When you get a chance Inform yourself on the % of weekly payroll taken in Employees/employers prsi + income tax taken from a trademan in 1967
Do the same thing in 1972 and every five years untill the retired ,
