> People who have a high amount of debt relative to income (generally the poor, the middle class, governments) benefit from inflation, not deflation, as they can spend full value money today and pay it back with diminished value money later.

But they keep having to pay more for Stuff. In other words, their purchasing power keeps decreasing, unless their wages rise to compensage for inflation. Deflation "means" an increase in purchasing power, which means getting more stuff for your money, which is.. good? What's not to like?
