       | 
       | That doesn't mean we're doomed to live out the idiocracy future,

           | Using your education to feel better than others doesn't serve
           | us to advance as a society. I suggest that if you're as smart

             | 
             | I think the issue is that there are two groups of smart &
             | wealthy people.
             | 
             | There's a mid-level of people who are happy to have more
             | than they need and don't have the Machiavellian drive to
             | extract every last ounce of money and power.
             | 
             | And there's an upper-level who are fine exploiting anyone
             | and everything.
             | 
             | There are of course altruistic people who are extremely
             | wealthy. But sort of by definition, the middle-level is
             | never going to have the drive & energy to fight that upper-
             | level, who's willing to do anything.
             | 
             | I guess my point is that there are two groups of smart &
             | wealthy people, and the ones complaining about the lower
             | class being exploited are not the ones who are doing the
             | exploiting. It's a classic setup where the upper class
             | keeps the middle class happy enough to not make it worth
             | the middle class joining the lower class in revolution. And
             | they aim the ire of the lower class at the middle class
             | while they exploit the lower class.

               | 
               | Basically, the environmental impact of having more kids

               | 
               | Ecological overshoot is a bunk idea. From wikipedia:
               | "Global ecological overshoot occurs when the demands made
               | by humanity exceed what the biosphere of Earth can
               | provide through its capacity for renewal."
               | 
               | Earth's capacity for natural resource renewal is
               | routinely increased by human activity.
               | 
               | For instance, when humans switched from hunting and
               | gathering to agriculture, earth's capacity for natural
               | resource renewal rose rapidly as many new reccuringly-
               | planted crops sprung up in places they never had before.
               | 
               | Another example, the invention of fertilizer. Food
               | scarcity used to be a real problem for large swaths of
               | the planet. It isn't a problem for most of the planet
               | now, in spite of the fact that demand has grown, and
               | demand growth accelerated by orders of magnitude relative
               | to e.g. 1000 AD. In fact, human activity has made the
               | renewal capacity for earth so much greater that we now
               | have an entirely different problem: for the first time in
               | human history, there are more people consuming _too many_
               | calories than there are people consuming too few
               | calories. Clearly, food isn 't the problem.
               | 
               | The sun provides enough energy to desalinate every ocean
               | on the planet hundreds of times over even with our
               | current rudimentary PV technology with efficiency rates
               | in the ballpark of just ~20%. Water isn't the problem.
               | 
               | While fusion may still eternally be 20+ years away, we've
               | had fission for decades now. You can power the global
               | electricity needs of twice the population of today's
               | planet with reactors taking up less space than Rhode
               | Island. The waste can be permanently and safely disposed
               | of continuously by launching it into the sun for
               | something like 0.000001% of the annual global GDP.
               | 
               | Of course, the sun is also blasting us with the product
               | of nuclear fusion constantly, so we could just massively
               | scale solar to humanity-sized installations. Imagine
               | using a bullet train to get from one side of the
               | humanity-scale PV installation because driving takes too
               | long. So ultimately, electricity isn't the problem.

               | In order for humanity to be able to run, we need to not
               | kill it right after it started crawling.
               | 
               | I must be missing something here because it seems like we
