Small iterative changes are fought tooth-and-nail by those emboldened through exploits encouraged by capitalism who, ironically, hold most the power to make such changes (not much unlike historical implementations of fuedelism).
The system itself is very self-preserving in that nature. Those who have the most to lose in the system have the most power and resources to resist change because that's how the underlying system is structured.
With socioeconomic mobility at an all time low due to earlier successes closing doors behind them (the "american dream"), it's no wonder people are growing more frustrated and seeking radical change over incremental changes. They've tried incremental change (and watched their parents and grandparents try it). It didn't work, so now they're pulling out the stops and who could blame them.
Look at the 2016 and upcoming 2020 presidential elections, largely fueled products of this issue in various forms. People are growing very tired of being lied to and exploited. The very wealthy groups, as the article suggests, need to consider that maximizing long term profits may require them to reduce their short term profit margins a bit and keep working classes from turning this entire country upside down.
