Sharing a living space over the last few years with a right-wing guy, I came face-to-face with a few annoying situations that could easily have been avoided by using a small amount of foresight. For instance, this fellow rarely took showers, for reasons unrelated to the subject at hand, but when he did take one, he would remove the small catcher that I had placed in the drain. Why? He had long hair, and when he took a shower, so much of his hair would fall out that it would clog the strainer and not allow the water to drain out. The longer the shower, the deeper the water would get if he left the catcher in the drain, so what did he do? Before he took a shower, he removed the strainer.
Why did this annoy me? Because, being the responsible one, I would inevitably have to get out the plunger and spend some work time with that bathtub drain at the point when the hair that flowed into it caused a clog further down. It occurred to me, on one such plunger occasion, that my housemate had provided me with the perfect metaphor for the right-wing approach to solving problems. He couldn't see very far past the end of his own nose, so he could not imagine what might cause the bathtub drain to get clogged.
During the Bush/Cheney era, we got used to hearing these right-wingers say "No one could have imagined..." or variations on that theme, when in most cases someone actually had imagined -- just not someone from their ideological circle. Pick a subject, from infrastructure maintenance to disease prevention, unemployment assistance to scientific research, investment in education to environmental protection, and the short-sighted right-wing approach will almost always lead to far greater long-term costs, even if it manages to achieve some small savings in the near term. Right-wingers do not see the long view, even when it's a matter of months rather than years, and they don't have enough brain cells firing at any one time to add up the logic of their actions to get to the inevitable sum of the results of those actions, so we put the future in peril whenever we hand them the keys to that future.
Beware of the right-wing politician who says he can save you money by not spending for that ounce of prevention -- most of the short-term benefit will go to the wealthy 1%, but even if some of it does trickle down to you, the bill for the associated pound of cure is guaranteed to cost you a lot more in the long run.
The idea of the 7th generation apparently comes to us from the Iroquois nations, where those chosen to lead the tribes and to make the most consequential decisions did so on the basis of how their decisions might possibly affect 7 generations of their children. With right-wingers, you won't get 7 generations of forethought -- you'll be lucky to get 7 minutes.
