Improvement of ones economic condition is the aim and object of a materialist, but there is no end to this material advancement, for if one cannot control his lusty desires, he will never be pleased, even if he gets all the material wealth of the world. In this age we see much material improvement, but still people are struggling to get more and more material opulence. Manah sasthanindriyani prakrti-sthani karsati [Bg. 15.7]. Although every living entity is a part of the Supreme Being, because of lusty desires one continuously struggles for so-called betterment of ones economic condition. To have a satisfied mind, one must give up his heart disease of lusty desires. This can be done only when one is Krsna conscious.
