|Extreme poverty statistics|
I'd draw attention to another consequence of these statistics. The omnipresent claim by collectors that all the unpapered artefacts apparently freshly-surfaced on the market 'could have come from' old collections ('people have been collecting ancient artefacts since....') is nonsense. the green area includes people with disposable incomes - potential collectors. It is very easy to see that in the decades preceding 1970, the number of people living above the poverty line was much, much smaller than today. It is quite simply a physical impossibility for there to have been enough antiquity collectors in the (pre-intrnet trading) world to have pre-owned the number of antiquities currently surfacing on the market. This is simply a highly-implausible lie.
I challenge any dealer in portable antiquities to produce verifiable figures showing I am wrong.
