In the current world, where do you think a lot of the capital class is able to get their capital?

Technological progress, and especially the Internet, has made much bigger markets out of what were previously lots of little markets, and now th "winner take all/most" dynamics make it so that where you previously could have, for example, lots of "winners" in every city (e.g. local newspapers selling classified ads), where now Google, FB and Amazon gobble up most ad dollars - I think someone posted that Amazon's ad business alone is bigger than all US (maybe more than that?) newspaper ad businesses.
