I'm not an economist, so maybe someone more knowledgeable can weigh in. But my understanding is that deflation is worse. If you can just stick $10k under your mattress and expect it to be worth 10% more in a year you have no incentive to invest. Businesses will just hold their cash, banks won't have money to loan out and the sort of investments that provide new jobs, goods and services are a risky high-effort bet compared to just saving.
