This article is a troll. It is not a good faith argument. It's an attempt to gain attention by saying something outlandish. The proper response to a troll is to ignore it.
There are real discussions to be had about how to best redistribute wealth to benefit society. This isn't it. Thy picked an arbitrary number and declared people with more money than that "bad" and "immoral". There is zero mention of what mechanism would be implemented to stop people from attaining more money than the arbitrary "bad person" number, so there is nothing to discuss in terms of whether this would be helpful.
