Well I entirely agree with you about that.
If you travel to the West of Ireland you will find the occasional famine museum, preserving the memories of the Great Famine of 1845 thru about 1851 (also known as the potato famine). Over a million starved to death and even more emigrated reducing the country's population by a quarter. Throughout this period Ireland remained a large net exporter of food, mostly to Great Britain, exporting well over what was required to feed the starving masses. Mostly this was the result of the fact that most of the good land that could produce grain and cattle was in the hands of absentee British Landlords, who had expropriated the land over a century of oppression and discrimination, and who could profit more from selling their products in the UK. Only the hillsides and the poor lands, suitable for potato cultivation remained in the hands of the native population who became utterly dependent on it for their survival. A persistent blight wiped out the monoculture and mass starvation resulted in the midst of plenty. Jonathan Swift parodied the English policy in his "A Modest Proposal" in which he suggested it might be better for the British to eat the Irish babies rather than starve them.
This is a constant theme in human history from China to Persia and Central Asia, Europe, Australia, South Asia and the Americas. The Irish Famine and the elimination of the Australian aborigines have been repeated countless times in the history of human civilization, and there is no reason to believe we have seen the end of it. Indeed we may be witnessing some new beginnings.
I agree with you about the ability of modern communications to trivialize information and understanding. Yet another example of unintended, unforeseen and unexpected side effects from new techniques and new processes.
"Pundits" and every other category of people includes the good, the bad and the ugly ... and everything in between. Discriminating among them is often hard and confusing, and very few are entirely without defect or some element of merit.
Greed and avarice are obvious and mostly bad. Power seeking behavior can be more difficult too evaluate. A great deal of misery has been inflicted on mankind in the name of noble sounding goals, and history reveals numerous tyrants who have slaughtered thousands or millions in the name of lofty aspirations. Remember Robespierre, Lenin and Jim Jones.
