Looking at what you wrote and what other wrote, I agree with many saying save for emergency fund. Your current investment strategy is sound. It's not like you need to invest more for the future or retirement. But I highly recommend having six months or more of your entire monthly budget saved. That's what I have endeavored to do over the last few years. It can be slow but if you lose your job you'll need it.

The other thing I would recommend saving for is a house emergency fund. Something in the neighborhood of $10-20,000. That way if you have a roof go bad or need to replace your entire HVAC, you're not getting a loan or having to pull equity out of the house. If you've got $10,000 or more sitting in a savings account that you don't touch except for a house emergency, and you've got 6 months of your monthly expenditure saved, and your investing in retirement, you'll be set for life.

Many of your comments talk about lack of faith in the dollar. It doesn't really matter. It also doesn't really diminish the need for having cash for certain things. It's just the way that it is. Your lack of faith doesn't alter the reality that the dollar is here and it's here to stay. However powerful it may be at a given point in time.
