It is actually something everyone should take into consider,as it's practically inevitable.
The question is not if,but when,and the predictions are bad.
USA just removed the debt limit of $17.8 trillion,and it already increased to $20,5 trillion,and this just sped the things up.
It is estimated the crash will be worse ,not from the one in 2008,but than the one in 1929!
So earn as much money as you can whilst things are still holding up,because we're awaiting some hard belt-tightening.
