So investing is needed in a free enterprise system to aid in expanding and growth. If everyone just spent their money instead of investing it, smaller companies would not get the capital needed to compete with the larger companies. This would lead to monopolies, loss of job growth, less taxes collected, ect. As long as we are investing in newer ideas and technologies, we will always have long term growth.
