I have long maintained that there is, actually, nothing new under the economic sun for (checking my watch for the precisely correct time) the last few thousand years or so, and if you look deep into my Serious Mogambo Eyes (SME), you will see, as the acronym suggests, total sincerity when I tell you that there have always been the usual few things; income, taxes, spending, saving, borrowing and debt, and something along the lines of interest, which is not to forget, of course, money itself.
