Well:

1. I would like to see strong progressive taxation that explicitly taxes concentration of wealth. This would be aimed at all large companies and wealthy individuals, and ultimately based on which actual human persons have legal control of the company such that it can't be gamed by creating shell companies, etc.

2. On top of this, I don't see why we can't explicitly put tariffs on things like financial or advertising transactions. Somewhat similar to a Carbon Tax, it would correct for costs to society caused by the activity. I'd be particularly keen on seeing measures that make it extremely expensive to do short-term trading, forcing investors to take a much more long-term view.
