I think cheap money expands the economy unsustainably. When you can't make any interest by saving people look for higher ROI via investing. I think in those climates VC money comes cheap, finances unsustainable business models, those businesses employ people which now compete against established businesses for talent and wages rise. With higher wages comes competition for a limited supply of goods and voila, the cycle of inflation. At least that how I understand it, but I'm no economist.
