If someone is investing in productive assets (companies, rentable property) for their sustained revenue potential that isn't a bad thing. Spending on goods and services will add demand to the economy and money will circulate.

There is also more reason to borrow in an inflating economy which adds money and demand to the economy. Obviously borrowing can get too high and needs moderation if bubbles are to be avoided but gentle adjustment is needed to prevent massive swings in aggregate demand.

Also I'm not arguing for high inflation just that even a couple of percent deflation could be really bad.
