Well, Layla, The gentry didn't need to earn money, they were 'independently wealthy' from inheritance and property. The profession of a man born into such a family would most commonly be stated as 'Gentleman'. But whatever the source of their income, less than 3% of the UK population had more than £160 per year. A skilled man, like the seamen on Titanic, earned about £60 a year. An unskilled labourer earned about £40 which, even by Edwardian standards, was well below the poverty line if, like most, he had a large family to support.
By contrast, The typical annual income of a well-to-do upper middle-class family with servants (the kind of people who travelled 1st class) would be around £2000. For them, the price of a basic 1st class ticket on Titanic would be equivalent to less than one week's income, but their lowest-paid servants, the most junior maids and pages, would need to work for 3 years to earn that much money.
Hope that gives you a basic idea of the range of incomes in Edwardian Britain.
