Capital has to be aggregated to be invested and made productive in assets that produce. Econ 101 tells you that captial is one of the factors of production in a capitalistic society as ours. When you attack wealth and try to confiscate it, through abusive or punative income taxes or estate taxes, you are attacking capitalism at its heart. That, along with Fascist-style control of products produced by business activity through onerous regulation, is what these leftist/progressive/socialist/Marxist/CommieRat Democrats in the White House and Congress have been trying to do to us. . . attack our capitalistic society at its very heart.
Capital is not only a factor of production it is also the most mobile of all the factors of production. That’s taught in Global Econ at the graduate level. I took that class last semester it was awesome. Our Prof shot down every progressive marxist kid that though they knew a hoot about real world economics with cold hard facts and GAO data.
