Even if they "acknowledge" it, so what? It's not their job to create extra jobs to replace the ones that they've automated out of existence. It's never been the jobs of the companies creating disruptive technology, like farm equipment or cars or computers, to do this.
It wasn't Ford's job to find new jobs for everyone who had a horse-related career; same deal here.
e.g. which society is better to live in:
(low inequality, less wealth)
10th percentile average wealth: 100
99th percentile average wealth: 1000
(high inequality, more wealth)
10th percentile average wealth: 1000
99th percentile average wealth: 1000000
Of course this is an oversimplification, but you get the idea: income inequality is not the only important factor.If the majority of people get 10x the money they used to, they're not getting 10x the purchasing power, because everyone needs a higher salary.
This is also an oversimplification. You can read more about the phenomenon here: https://en.wikipedia.org/wiki/Dutch_disease
