Illusion of money
Here is the perfect example of an illusion: money (or currency if you prefer). For this illusion, humanity allows itself to be manipulated, killed, destroyed and created a hell.
Those coins are only one example among many others. Those are 50 Belgian francs coins, which before 2002 were worth 1,25E and were wanted by some, are worth virtually nothing today, just the price of nickel (a few cents) ... and it is for that illusion that lots of humans destroys everything around them !
Your absolute right but when your blinded my greed an illusion of your desire will always cause you to stop at nothing to get it. Which I believe is just a natural instinct to survive we are from the animal kingdom after all. Just like animal not everything is a pretty site.
