If everyone's real wealth doubles, that is great, but it is not a stable equilibrium.
If a very small percentage of the people own a large percentage of the wealth, it compounds. They literally cannot spend all of their income on consumption, except maybe by lighting piles of cash on fire, but that is not a route to doubling the real wealth of everyone in society.
That means that asset prices rise, and fewer people can afford property. Jobs concentrate near where rich people live, because they are the ones with disposable income to spend, making this worse. Transfer payments (rent) from ordinary people to the remaining property owners are high. Wages stagnate, because wealthy people spend most of their money on assets, not goods and services. Consumer demand decreases. Capital moves away from producing things that ordinary people need, because they can no longer afford them, and is instead allocated to producing luxury goods. Social mobility is low because low wages and high property prices make it impossible to work your way up.
The cycle is self-reinforcing, not self-correcting. Most of history throughout the world has consisted of a few very wealthy feudal lords and a large population of serfs.
Strengthening the political system might be nice, but post-Citizen's United, that does not seem to be the direction the US is headed, at least, nor is it in the interests of those who benefit most from the current system.
