The new racism

Why are three of the planets in our solar system dead?
Venus and Mars once had habitable climates and a planetary cousin. Today venus is overheated while mars has cooled and the mysterious fifth planet is a ring of debris and captured moons. The map of our solar system reads like a devastated battlefiald. If our people are truly the only survivors we may have something to answer for, if not then we're in big trouble.
The solar system offers a myriad of places for people with spacefaring abilities to grow a civilization. With earth as a farm and hunting ground, asteroids for easily segregated minerals and moons full of water and hydrocarbons someone who could move about might live almost anywhere. The last place a spacefaring culture would call a permanent base would be a planet. Planets are immobile and ultimately undefendable, not to mention the added expense of fielding and maintaining land equipment, machinery and forces. In a word it would require domination, when in space that is already achieved. It would be much easier to maintain a covert presence and control the populace using it's own systems.
Wealth is the gateway to earthly power and a spacefarer would have acess to resources, power and technology beyond that of the planetarian. Wealthy non-celebrities are also, typically, the most inaccesable of folks, any attempt to see, speak with or photograph them could easily be seen as espionage for nefarious purpose. In fact a spacefarer could lead a comfortable, shielded life here provided no-one found out what he is. If there were many of them they would co-operate with one another until they held the control positions that are important to them.
Militaries are harmless to them so long as they are air, land and sea surface based. Technological achievements beyond this comfort zone would have to be curtailed to alleviate the need for genocides. As long as we can't get to them or carry out space warfare we are allowed to live but once we can an ice-age or flood are sure to be imminent.
With the level of technology and ability reported by pilots and trained observers we can easily imagine them occupying any part of the solar system, even the ground beneath our feet and the water beneath our submarines.
Their secretiveness, an evidence of their power, is carefully protected by our own institutions, although this does not mean there is collusion.
In the area of resource and industry they would want the unaccountable positions, the kind that could aquire colonial size shipments under their own oversight.
The enemy is already here, the enemy is within, they are the ones disarming and diseasing you, they pollute the bodies and minds of your children that they might die sooner.

The new Racism.
I will hate those that are alien to my planet. I will not give them succor nor aid but will wrench every advantage from their living or dead bodies. I will fight them to my last breath and if my soul go-on I will fight them still.
