a. The distribution of income has shifted to higher earning individuals who save more than lower-earning ones.
b. The most successful corporations today like Apple or Google do not purchase as many capital goods for their business compared to companies in the past such as railroads or steel plants.
c. Interest rates are close to zero now.
d. Technological progress has reduced the prices of capital equipment.
e. Financial regulation has made it more difficult for banks to extend loans.
