The top 1% always win in certain nations simply because the laws, regulations, trends are all heavily influenced by lobbyism by the 1%. If all tax loopholes were closed, the passing of wealth from one generation to the next was properly taxed, private equity holdings were properly taxed, and if proper regulations were enforced to reign in monopolies and oligopolies, and trillions of tax payer fund transfer to the military complex discontinued, then the story would look very different.
The story looks very different for the 90% wage earners. Hardly any participation in productivity growth. All those increases went into the pockets of shareholders and the top 5%, hardly any of that ended up in the pockets of those who do the actual work. https://www.epi.org/publication/charting-wage-stagnation/
