A quick question for economists: Would a slow rate of deflation be bad?

So, we have a current rate of inflation, meaning we can buy less for each dollar we spend, right?

Why wouldn't the inverse be a better thing? A slow, measured deflation of the economy, allowing each dollar to buy more.

Would this not help us get back to a place were a single income could support a household, and a bachelor's degree could be worth more than the paper it is printed on again?
