We've had a 'boom and bust' (artificial bubbles) economy since George Washington's day. Historically the wealthy 'always' come out of these cycles with more wealth…and as you said….the rest must 'again' try to catch up. None of this is new….except the advancement of technology.
The Reason; simply put….these 'bubbles' are the manipulations of the greedy, those already well-off and 'self-entitled' who are NEVER satisfied and never will be.
IMO; It is a form of mental illness enabled by our own society. In fact; we make little KINGS and QUEENS out of them all.
FACT; We have nearly run out of things to 'create' these bubbles. Our 'homes' were the last tangible thing that could be used by the elite to create 'real' wealth for themselves without actually working for it (Insanity Capitalism or capitalism for the Rich).
DEBT seems to have taken up the slack for now…Income from 'other people's debt'…go figure.....but as we know….most debt is an illusion, in that there's not enough MONEY in the world to EVER pay it all back….not that paying it back was ever the intention.
Another possible bubble occurring right now is connected with the "World Wide" purchasing (some will call it theft) of 'Mineral and Metal Rights and CONTROL' by the Biggest BANKS on the planet…..think about that for a moment……BANKS owning (and hoarding) minerals and metals……..I can smell another boom and bust coming our way….can't you all?
Like I said; We're running out of 'things' to create bubbles/speculation that have historically been used by the wealthy to create MORE wealth……..but they are a 'tricky' lot, don't give up hope for their future success (our failure) yet
