If your objection to the richness of the rich is a claim that it is causally responsible for the poorness of the poor, then you are interested in underlying mechanisms described by the distribution.
The mechanisms entail a particular distribution, or family of distributions, and in this case the mechanisms are underspecified given the distribution. (Hence my pointing out that the phrase "the rich are being increasingly favoured" "is quite consistent with the underlying power law being constant over time".)
"Increasingly favoured" is a statement about mechanisms. If the mechanisms remain the same as the population increases, then every individual who ends up rich is still working within the same mechanisms. It's just that when the population increases, chance alone, operating on the same mechanisms, will produce many richer individuals.
Technically, the population top centile is a biased underestimate of the distribution value even for a thin-tailed distribution, but for those distributions the bias is unmeasurably small with country-sized populations.
"Increasingly favoured" is a statement about mechanisms.
When you personally state it, or in general when it's stated by anyone? If the former, fair enough. If the latter, I disagree (cf. the last paragraph of an earlier comment). As a down-to-earth example, if I lost a game of Monopoly to you and afterwards ruefully remarked that "the dice were favouring you more & more towards the end", I would not automatically be accusing of having swapped the original dice for a different set of dice partway through the game.

Politics as gymnastics for rationalists. No one one Less Wrong is quite sure why politics is a taboo topic or how things got to be that way. What we do think we know is that politics is a great way to bring out the irrationality in people. So why not take advantage of that and use politics as a way to measure rationality? Since politics brings out the most irrationality, it should provide the strongest signal. Since there aren't useful objective metrics of how a political discussion went, we'd have to use subjective judgements by neutral third-party raters, kind of like they do in gymnastics. (In the comment thread for this post, feel free to find fights that you have no dog in, improvise a rationality rubric, and grade participants according to your rubric... let's see how it goes.)
Be a sheep. This is probably the exact opposite of what you were taught in your high school civics class. But if my friend Jane is more intelligent, more informed, and less ideological than I am, it seems like voting however Jane is going to vote is a strict improvement over voting however I would naively. It also saves me time, and gives Jane an incentive to put even more time in to carefully considering political issues since she now controls two votes instead of one. Done on a large scale, this could provide an interesting twist on representative democracy. Imagine a directed graph where each node represents a person and an edge is directed from person A to person B if person A is auto-copying person B's votes. There's a government computer system where you can change the person you're auto-copying votes from at any time or override an auto-copied vote with your own personal guess about what's best for society. Other than that, it's direct democracy... all bills are put before all citizens to vote on. Problems this might solve:
