Why should the other parties succeed? IE the aggregator sites? Is it merely because they exist?

If I make an aggregator aggregator, should I be able to demand placement on Google search results above mere aggregator sites?

Other parties should succeed because it's good for me, the consumer. If I need to take a trip, it's not in my interest at all for Google to be in the value chain and for me to pay the monopoly penalty as a consumer.
