'Consumption is good' is a crappy statement because it implies non-consumption (ie, saving) is not good. The proper way to state that proposition is, perhaps, 'want satisfaction is good'.
First, understand the basics of capital theory. In a really condensed nutshell, there is more than one way to produce a good. There is always a way to increase quality or quantity of production by extending the length/period of production. Extending the production process requires saving.
Production of consumer goods should match demand, which will automatically take into account savings. To say 'consumption is good' or 'saving is good' misses the relationship between the two. If consumption and saving are determined by individual preference, things don't go haywire. If you try to stimulate one side or the other you are looking at the disaster we're in now.
