The productivity increases of the modern times led to a corporate class. These oligarchs have eschewed the progressive initiatives, in eager pursuit of even greater wealth, supported by the wholly owned media and a bribed political class. What has been more evenly distributed globally is the ever-growing poverty, pollution and apathy against these powers.
To be fair, some improvements have been made, even at the feet of these giants, driven by government action and populist initiatives. This has been at the cost of concentration and increases in pollution and poverty in the poorest nations. The future looks bleak today, as the divide grows and progressive progress has all but halted.
