What's holding us back from affordable healthcare and houses? Humans.

What's holding us back from affordable spaceplanes and cool rockets? Physics!

When I fight with humans, people get angry with me.

When I fight with physics, cool stuff happens and physics doesn't (usually) get angry with me!

So, for a conflict-averse nerd who likes to dream about cool stuff, spaceplanes > endless committee meetings.

Any more questions?

Those rich enough to not need (young?) or have any healthcare they want/need and egoistic enough to not to care about housing (for others).
