I generally agree that the "sharing" economy isn't a sharing economy. But I don't think this:

  If it were a real sharing economy, the developers and system
  engineers on the platform would make the same hourly rates as
  the drivers. In such a way everyone would contribute to the
  co-op and everyone would benefit.

Different services are worth different amounts depending on the value they yield and, sometimes, who they're targeted at. If a relatively small team of programmers can enable a massive business, then they may be deserving of apparently outsized compensation for their time and work.

This is the leak that connects "sharing economy" with real economy. In a proper sharing economy (e.g. couchsurfing), you don't have compensation.
