I don’t think PG is necessarily saying that income inequality is not a problem. This is disingenuous on your part. Saying “of course the Gini coefficient is increasing” does not necessarily translate to “income inequality is not a problem.” Rather, what he is to my mind correctly pointing out is that the entire situation regarding wealth accumulation, distribution, and class mobility is perhaps more nuanced than we typically understand it to be. Indeed, he points out that it is in fact easier in some major ways, which is a wonderful thing to realize. This does not necessarily mean that income inequality does not exist or is not a problem. There may still be ways in which it is. Instead, it is good to acknowledge that the ability to build wealth through starting businesses is, in his particular lens, better than it has ever been.
Further, I think it is disingenuous to compact PGs meaning to “‘people like me are creating a lot of value, please acknowledge it. Also there are no downsides to this accumulation of wealth.’ ... it just seems like a desperate play to keep his wealth intact.” So much of the time argument betrays the arguer and rather demonstrates a perverse inclination to emotions such as jealousy rather than reasoned indifference. Why is he desperate in this case? Is he afraid of people taking his money away from him? Are there people actively attempting to do so? Is this not a natural human inclination? Is this something that only affects the wealthy? Do not all of us to a certain degree wisely protect what we have earned? It has indeed gone out of fashion to point out that the rewards of benefitting society are equal to the benefit ie what society is willing to pay for those benefits (if not less so, due to the existence of taxes). We should first admit that society is made of industrious and lucky individuals by varying degrees, admit this, and then stave away jealousy at the success of those more industrious and lucky than you or me - for success coming to the industrious and lucky remains just despite the existence of those who pursue lives of industry and are not as lucky. It is out of fashion to point out the simple and bare fact that ambition to improve the world is amplified in the environment where it is incentivized: if this be done through the respect garnered as a result of benefitting the world, that is great; if this be done as a result of rewarding the creator of those benefits commensurate to the benefits given, that is great also. In either case, the results are amplified; with both cases the results are amplified still further by the addition of the incentives. Yes, indeed the numbers by certain statistical methods appear disproportionate within studies of income inequality. Yet, simply because these figures impress upon us a knee-jerk reaction to decry the accumulation of great wealth by the few as unfair, does not make it so; it does not necessarily mean that something is wrong that these results should be allowed to occur. So long as the majority of we who inhabit the economy are not actively oppressed by the creators of great wealth, so long as our freedoms are not taken away, no reasoned argument can point to why the accumulation of great wealth is a damaging thing. Indeed, if it results from the great mutual benefit to society, this is in fact a very good thing. So long as the accumulators of such great wealth are not oppressing the majority of participants of the economy, the accumulation of great wealth ought to be a sign of the great benefits that the accumulators are providing to society, as it is society, as has now been remarked a number of times in this comment, that is paying for it. Indeed, if we continue to demonize wealth creators and go on to pass reforms that remove incentives to wealth creation, we would only de-incentivize the creation of future benefits to ourselves as members of society. Further, with certain reforms that constitute graded barriers to success, the freedom of economic mobility then being lessened, the entire economy and state as a whole is then oppressed by degrees - the oppression is then rather achieved by those who have sought to fix the “problem”. I’m not saying that income inequality does not exist - I’m saying that in this particular form the fact that there are disparities in income is not unfair, and that results from the just distribution of benefit to society that society is happy to pay for is not necessarily unjust by statistical analysis of income data alone.
