Should Jehovah’s Witnesses prepare for financial collapse?

QUESTION: With the upcoming financial collapse, what are we really supposed to do? I have a wife and a 8 week old son at home, so I'm obviously concerned with their well being. Of course, ultimately it is Jehovah who will save and protect those that call upon his name and do his will, but is there anything we can do in order to sustain our family? Should I withdraw all my savings and keep cash on hand? I assume money will soon be worthless, so is there a point to that? Will Jehovah let me and my family starve and die? I'm not sure if you have children, but I'm sure you understand my concerns.
