Well, I wouldn't assume that DEBT will be cancelled at the same time our savings/checking/money market accounts are frozen "for national security reasons".
So you might want to pay down your debt if nothing else -- at least it allows the banks to lend out less money to others :)
Every 1,000 in the bank is 10,000 that can be lent out at interest (thanks to our Fractional Reserve banking system)
Who knows if they're planning on rounding up people into Debt Prisons as a way to neutralize certain annoying people in the population.
What should you use your withdrawn money for?
Well, things you can eat/use/keep warm with.
Gardening supplies, organic seeds (that produce fruit with viable seeds), shovels, wheelbarrows, axes, wood, canned goods, dried meat/fruit, $5 jars of nuts, medicine, vitamins, bottled water, solar oven ($200), camping equipment (propane heater, stove, etc.) water purifying equipment, military surplus survival equipment, sewing machine, cloth, extra clothing, rope, large garbage cans (for growing potatoes, storing water, etc), and many other things you can probably think of.
As Catholics, I would recommend against heavy firearm acquisition -- except maybe something to kill wild animals with (for food). We're not pagan survivalists. If they come to my door to take my family to a FEMA camp, we're going to go peacefully. Hopefully we can convert many people there.
Most of these things would be great to own anyhow -- and you're not going to regret having any of these things. The list is a mile long, really.
In the meantime, spend any "normally wasted" time on developing a down-to-earth skill. if you have no downtime (or extra money), then God will take care of you. But those of us who DO have extra time and/or money, had better spend it wisely -- Because THAT might be the main way God is going to provide for us :)
Namely, giving us a heads-up so we can prepare a bit.
Besides, if something happens, and EVERYONE is losing money, you all will be experiencing an angst that most people will NOT be experiencing. Because THEY didn't read CathInfo.com, and THEY didn't see it coming, unlike you :)
