The less is spent on consumption as a percentage, but that doesn't mean they're not consumers at all.
True, but completely irrelevant to the discussion. As I said, you should not treat a variable as if it were an on-off binary.
And as I already stated savings are just as good for an economy as consumption is.
No, saving is either better or worse, depending on which of them already exists to excess, since they have an inverse relationship. In a developing economy trying to bootstrap itself from agrarian to industrial, saving is BETTER -- capital formation is the first thing needed to build an industrial economy; wealth distribution and demand maintenance can come later. In a mature industrial economy, however, the normal tendency is for it to be WORSE. (If it's a capitalist economy. A socialist economy like the USSR develops other problems.)
The reason for that is because capitalism has a natural tendency to give rise to increasingly unbalanced distribution of wealth and unsustainable concentration of income. When there is more capital accumulated than there is consumer demand to justify it, the excess goes into rent-seeking, bubble-blowing, and economic strip-mining that are more harmful to the economy than not.
