Tolkiens poor or rich? (UK Land Tax Redemption, 1796-1822)

I have decided that it is time to compare the incomes and taxes of two London Brothers, John Benjamin Tolkien (1752–1819) and Daniel Gottlieb Tolkien (1746–1813). I have used the data from the UK Land Tax Redemption published on Ancestry.co.uk where we can read: "The land tax was introduced in England in 1692 as a means for raising government revenue and was not done away with until 1963. Land tax records are of value to genealogists because they often list both property owners (proprietors) and tenants, placing them in both a parish and a year":
