The classical liberal view saw capital as part of the means of production. The Austrian School emerged from the classical liberal view.
In Das Kapital, Marx took the term "capital" and formed an ideology around it. Marx provides a totally distorted view of the way markets should work. For some odd reason people rejected the classical understanding of markets and adopted Marx's definition.
BTW: I like the Austrian school as well. It provides cleaning thinking about economic matters than the modern view which provides an unbalanced understanding of the markets.
If supply>demand you invest in liquidity in the market, the retail side.
If demand>supply you invest in production and manufacturing.
Lol now just to get Hive rich enough to venture fund one of these theories and get some tangible datasets to pick a business plan from.
