Does anyone in here participate in the so-called Underground Economy? Basically what this is trade or exchange of goods and services by either barter or straight cash. A couple of people I know do engineering work on the side or under the table.. I've known people who were good at fixing cars doing it for far less than what shops charge, for cash. Most of this is income they don't report. This is apparently becoming more popular as taxes become more crushing and people have access to mediums that allow them to network with each other. It sounds like a good deal to me. I've been thinking a lot about my skills and how I can participate in this economy.
