Compound interest, and as (admittedly) an armchair economist I buy into the argument that goes along the lines of:
"when the rate of return on capital (r) is greater than the rate of economic growth (g) over the long term, the result is concentration of wealth".
In my view, r has been greater than g for some time now.
> Then you might ask, if that's true, do you I want to enforce equality, potentially dragging down the economy to mediocracy (for example many stagnating European economies) or maybe accept that current nature does not meet our societal desire for equality.
To me, it is clear that while Europe optimizes for quality of life to a large extent, Americans really drink the coo-laid and enthusiastically optimize for shareholder value. I highly encourage you to give life in Europe a go at some point. I hope you'll return (or stay) also having reached the same perspective.
