Rent, profit and interest are the three classical returns to owning capital. Gary Stevenson argues they are functionally the same thing, dressed up in different legal scaffolding to obscure how alike they really are.
He has a point. The legal and tax structures are genuinely different, but at the level of household cash flows all three are payments from someone who works for a living to someone who owns an asset. They are all passive income for somebody else.
Where the argument gets uncomfortable is at the line between exploitation and ordinary participation in the economy. A pensioner with a workplace tracker fund is technically extracting all three. Most of us are on both sides of the ledger.
The takeaway is not moral, it is practical. The economy rewards asset ownership. Shifting your income mix from labour to capital, via ISAs, pensions, and any other wrapper you can reach, is the deliberate move on the board.
