Taking it seriously is fine, but it doesn't change anything, it's just general opinion.
What changes things is a concrete plan, or at least the outline of one. One doesn't exist because it can't exist. Numbers don't lie. So, we get stuff like what's on Biden's web site which to me reads like some high school project, it's not serious. It's puffery.
And again what we do HERE is a small piece of the puzzle. The numbers don't lie.
Politicians are making rather gradual changes for votes so they can look good, but it simply is not nearly enough.
