The ultimate problem is that people want "unicorns for peanuts". Google, Facebook and a few other large tech companies have hired most of the top of the labor market, the "ferraris" in your analogy. Most companies want the ferrari but can't afford the price when others are willing to pay much much more.

The only way to really balance the market is for more of the talented engineers to start their own companies (reducing labor supply and possibly increasing demand). Arguably the proliferation of one-person or small bootstrapped startups is a reflection of the state of the labor market.
