The American saving rate is up to 7.8% after dropping to 3.2% by 2009 and the financial crisis. This is a good thing as Americans save for retirement and avoid extravagant expenses to build a safety net. The collapse of traditional pensions means much of the burden for retirement falls on individual families. The student debt burden means families share in high education costs, and the lack of a cost efficient health system means more money is needed for health expenses than in other advanced European countries. The savings rate is still nowhere near what it used to be in the 1970's. 

Higher savings also builds up the funds that are in banks as savings that can be a pool of funds for use in building national infrastructure and other value adding investments for the country. China has used a high savings rate and savings pool of funds for its extensive infrastructure investments that modernized the country.
