into small scale farms. Urban terraces could be formed to grow organic produce that could then be sold in the city at 100% markup to the more affluent inhabitants of said city. That's jobs, money, and food back to the community right there.

Collecting and breaking down obsolete or broken electronics and appliances into copper and other reusable materials could also perhaps provide employment to the minimally skilled.

Bottled water production using tap water with sales being made to Africa or other 3rd world economies could maybe create jobs.

Lastly a number of folks could be trained as security for overseas work as mercenaries (high risk high reward) or security detail i.e the real "black water".
