What people usually mean by this is that people dont spend and consume. But when people saves, they send the money to the bank, that loan it out through fractional reserve banking, thus promoting investment and (usually) creating growth. So by not consuming and saving more growth is created.
This thesis is proven by several economic professors.
This does not say much about the theory.
