Regular people are getting wiser on their financial management day by day. For sure they have realized that dollar is getting weaker and most of the basic needs are getting expensive. In the years that will come, their savings will be worth nothing if they'll let it sit there and rot. I don't knoe much about other countries but I am sure that those people who dump their dollars are planning ahead for their retirement, before they'd have limited options to only savings in the bank, but now that there are lots of access and information you can get through internet and web, they can expand their options to so many choices now.
Governments seemed to actually believe they could maintain people ignorant about the realities of the economy of the world forever, an impossible goal in a world which is interconnected and that allow us to know what happened at the other side of the world in a matter of seconds, and as such the people that understand the current economic model is nothing but a fraud are already taking countermeasures to protect themselves, and as time passes the more evident this will become.
