Is inflation a good or bad thing? Why do governments want some inflation?

Money, credit, bonds, and the stock market are mankind's cruelest jokes. We have no better way of transporting value so we base value on consumer confidence. It's just as silly as basing value on the supply of gold.

Is inflation good or bad? I'd say inflation is good if it gets businesses moving. Inflation would be bad if currency became devalued and consumer confidence dropped.

The world's fiscal system is in crisis and people living in communities which don't create value are suffering.

Is it even possible for the majority of a country to create value? The system seems unsustainable to me.
