Murder for money is purely one sort of making a living, one in which the murder is incidental to the goal. Those people who are involved in this business can easily be move to any other by offering more money.
The most famous example of someone - indeed, one of the earliest motives attributed to the Ripper was that of profit; what else could he be doing with the body parts that he took? Even today, one hears tales of the 'Jack The Ripper' who was in the East End at the time of the murders, seeking to buy 'pathological specimens'. If profit of this nature alone had been the Ripper's motive, then a poor job it was, since two of the Canonical Five had no organs whatsoever abstracted. In this case, the potential reward hardly warranted the incredible risks, and very few Ripperologists today lend any credence to 'profit' as a motive.
Yet, there were other, less obvious methods of profiting from these crimes. Could the White chapel Murders have been the work of a Victorian hit man, for example, someone who had been hired to do grisly deeds that another was himself afraid, unable, or unwilling to do? Or were the murders committed merely to drum up business in some other area such as with private detective or security firms like Pinkerton's? Or were they calculated to drive down property values in the East End so that they could be bought for a fraction of their former value? After all, the Victorian Era was also the age of J.P. Morgan and other flint hearted businessmen, many of whom were enormously wealthy, worth many millions of dollars at a time when an ordinary working man made considerably less than $2.00 a day. If such a businessman or a developer were to have coveted the East End property due to its proximity, say, to the Bank of England, then such a plot could have conceivably arisen. This theory is supported by a similar situation found in Houston today. Houston's 4th Ward, actually within walking distance of present downtown and close to the exclusive Theatre District, is an old slum that has been encroached upon by urban sprawl to the West. Properly developed, this land would become immensely valuable, and developers have in the past tried various and devious means to gain title to it, the last of which was to have many nearby inhabited apartment buildings condemned, the working-poor occupants forcibly evicted, and the buildings quickly razed. Political outcry was so great that too many people took notice of what was going on and so these attempts have quieted for the while. But the land is simply of too great a potential value for avaricious developers to ignore for very long.
