There are many definite methods, honest and dishonest, which make people rich; the only instinct I know of which does it is that instinct which theological Christianity crudely describes as the sin of avarice.

Summary

This quote suggests that there are multiple ways to attain wealth, both ethical and unethical. However, the one innate impulse that consistently leads to riches is identified as avarice, or greed, as depicted in theological Christianity. It implies that regardless of other strategies employed, the drive for accumulation of wealth is a powerful force that motivates individuals towards financial success.
