Unfortunately, your young friend, Trivedi, will not be able to appreciate the important connection between optical illusions and 'MLM' scams. However, if he is able to follow the BBC article, he will discover just how easy it is to fool the human mind, particularly, our visual sense; for an individual's model of visual reality depends on the context in which he/she sees something.
The minds of unquestioning 'MLM' adherents, like Trivedi, have been programmed to look at 'MLM' scams in the reality-inverting, 'positive' context of: 'Business', 'Independence', 'Financial Freedom' , 'Direct Selling','Low Risk' , 'Income Opportunity', etc. This reality-inverting 'positive' context has been further confirmed by (apparently independent) : celebrity endorcements, glossy-advertizing, 'Direct Selling Associations' , etc. All of which have actually been financed by the profits of 'MLM' scams.
It is only when you take 'MLM' scams out of their artificially-created 'positive' context, that their true absurdity, and danger, appears.
To give your free-thinking readers some idea of the mathematical absurdity of the entire 'MLM Income Opportunity' myth, I recently posted the shameful transcript of a 'video message of support' made (in 1999) by, 'MLM' useful idiot, Tony Blair (at the instigation of the silver-haired Director of the so-called UK 'Direct Selling Association,' Richard Berry), in which the former UK Prime Minister spoke of almost 500 000 'Direct Sellers'in the UK. Unfortunately, at that time (according to his own government's statistics), there were less than 24 millions households in Britain. In other words, Mr. Blair was unable to see (due to the artificially-created 'positive' context in which he'd been shown 'Direct Selling') that each so-called 'UK Direct Seller' had less than 50 households as potential customers.
In reality, effectively 100% of all the tens of millions of transient persons around the globe who have signed reality-inverting contracts with so-called 'Direct Selling' companies during the previous 50+ years, have not received one cent of net-income (let alone earned their living) by legally, and regularly, directly-selling products, and/or services (supplied at a controlled-price and quality by these companies) for a profit, to persons who were not under contract to the same so-called 'Direct Selling' companies.
Far from being an authenticincome opportunity, 'Direct Selling' has been the reality-inverting 'positive' label for one of the most-extensive, and sustainable, closed-market swindles of all time.
