It takes alot of management and political will to support the middle classes. Since extreme free market capitalism (as well as communism) will lead to 0.1% owning all the wealth. History shows this. So - when a technology comes in that threatens the existence of the middle classes it needs to be addressed since the problem will not magically fix itself.
This is also the crux of what the interview above was saying as well.
