From some people, no call comes without a request for money. “Nowhere to hide,” the authors heard, and “it is a curse more than a blessing.” This is a familiar problem to any parent with a child in college; every society has some level of ritual and social expectation around cash.

There can be no mobile economy until cash loses some of its ritual social meaning. This happens with economic opportunity—the economic opportunity that mobile money is supposed to help provide.
