"And very often the influence exerted on a person's character by the amount of his income is hardly less, if it is less, than that exerted by the way in which it is earned"

This quote by Alfred Marshall recommends that the amount of money a person earns can have a substantial influence on their character. This influence might be just as strong, if not stronger, than the way in which the cash is made. Marshall is suggesting that the quantity of cash an individual makes can shape their character, regardless of how it is earned. This could be through the power of money itself, or through the lifestyle it can supply. For example, an individual who earns a big salary might be able to manage luxuries that others can not, and this might form their character in a specific way. Alternatively, a person who makes their cash through hard work and dedication may establish a strong work ethic and a sense of pride in their achievements. In either case, Marshall is suggesting that the quantity of money a person makes can have a profound impact on their character.
