The retail bank in no way makes Joe Average far richer than he already is by his own efforts. And I don't think those Russian billionaires invested in Facebook just because they were yawning at the thought of depositing the money in a bank and the boring routine of such a transaction. They all expect huge capital gains and the pump-and-dump institutional machinery of Wall Street is the instrumental system for this. |

To address your points - you're ignoring the difference in financial goals and economies of scale.
Joe is an employee. So his goal is to preserve the capital he earns, which is a service the retail bank offers. He earns a paltry interest on his money because 1. the bank lends his cash out very conservatively, and 2. he's not paying for the service of having it actively managed by a professional.
Rich people can not only afford professional money management, but very wealthy ones typical have access to higher quality investment vehicles than less wealthy rich. And since they have more capital (that they don't need) than Joe does, they tend to tolerate more risks. They also tend to get the rewards of that risk when its professionally managed.
At that scale of money, investment can have positive externalities. The capital invested in Facebook, Google, Apple, etc directly helped create jobs and expand the technology sector. Joe's money did comparatively little. Both are rewarded for their proportional economic impact. Capital gains is an incentive to keep rich people from parking their cash at a retail bank. Whether it works 100% effectively is definitely up for debate. But the general idea is that their cash can be deployed in a way that not only makes the rich richer, but the rest of society as well.
