=======================
Fundamentally, the bubble have already gotten wayyy too big -- Obama, instead of fixing the underlying problem, allowed the issue to continue by bailing out the broken banking system (taking tax payer's money to feed the welfare system for the big corporations and the mega wealthy -- where the CEOs and corporate executives had continued to shamelessly pay themselves massive bonuses and pay-cheques after collapsing the economy, while cutting jobs and pay for the middle class staffs; and after that, Trump continue to feed the bubble into the monstrosity it is today (with debt that needs to be paid back sooner or later).
Trumps's answer to the crazy US debt? "Easy we can just print more money".
