With progressives, I agree on the basic premise: society should move forward.
However, that is the opposite of what Progressives nowadays do. They sit around looking backward, trying to invent enough guilt so that they have an excuse to divide up the wealth of the past.
Progressives after all brought us programs like eugenics, or the idea that we should encourage healthy breeding. They originally were in favor of subsidizing exploration, adventure, and sane normal living, so that our civilization could become more advanced, although this was in a Nietzschean sense and not a Marxist one.
I would say that I am a Nietzschean Progressive. I think we are here to do more than eat and shop, and anyone who does not have three-quarters of his time to himself is a slave. I think we need to leave as close to zero impact on the environment as possible, and this means that not everyone can do or own everything that they want. I believe we need to explore the stars, but agree with Ray Bradbury that what is holding us back is our disorganization and moral confusion within. The frontier is us, in other words.
I do not have a problem with eugenics. If you want to abort the retarded, gas the insane, and sterilize the criminals, this strikes me as forward-moving. We either accept natural selection or our ignorance of it destroys us. On the other hand, as a Progressive I could never support the subsidy state, since it works against natural selection. Flat taxes, no welfare, and no entitlements all the way.
I think we should allow people more flexibility with what they do to their bodies, not so much from a "muh freedom" point of view but one of progress. Let us see how everything turns out. Without us supporting their healthcare, they can take any drugs they want, medical or illegal, and purchase any operations they want. You can be a transgender steroid abuser on LSD and heroin, in my world, but no one is obligated to help you if your liver launches itself into the street or you have no retirement fund. Welcome to freedom; it comes with natural selection, and sometimes you are what is being selected out.
I find the "Green New Deal" to be far too limited. In my view, we would simply set aside half of all land for nature and keep humans off of it. We could license and indemnify snipers to enforce this; if you are seen in the green belt, the only thing you can expect is a 7.62x39 winging itself through your vitals. It also makes zero sense to pay foreign aid to, or interact with, the third world, since its population explosion threatens all of nature.
At the same time, I know that this Progressive attitude benefits conservatives. Our methods are heading in the same place and work better. We make healthy families, and those make healthy families, and those genes persist while the flaky Leftist lifestyle leads to ruined families and neurotic children. If we implemented full Progressivism, in a few centuries you would have nothing but actual conservatives.
