Again, that’s like saying inducing vomiting would just be “undoing the eating.”
But for what? What individuals benefit from tanks? (And technically building tanks is an investment in production. Unless the government is buying the finished product from somewhere else, this can’t be considered “immediate consumption”.)
And paying people to not be productive only reduces the total productive output of the country…thus making everyone poorer overall.
Read this and watch that first video.
That’s basically what I already said.
But what’s more, odds are the taxes would actually hit the sustainable, actually-demanded projects quite hard…as they may very well be the most profitable and therefore the most ripe for taxation…just like bailouts take from the successful to prop up the unsuccessful.
What capital? The whole meaning of “overinvestment” is the fact that the capital necessary to finish the projects isn’t there in the first place. Please see here, and for more info here.
Kind of. But you’re missing the whole part about this being an actual economy and not a math equation. Again, you can’t just eat something and then barf it up and expect the result to be the same as if you never ate it. These manipulations have real effects. Even “taxing out the new money” and trying to shut down the malinvestments would lead to more distortion and more suffering.
