we don't need shareholder growth capitalism as it stands... we need sustainable capitalism that is in it for the long term. no clue how to achieve that as it stands though and ceos have short term goals/bonuses tied to short term profits.
Another (perhaps more drastic) approach would be to force shareholders to hold their shares for a minimum period of time, or institute a mechanism that distributes losses across the shareholders of the last X years. That would incentivize long-term investment strategies over short-term rent-seeking.
Or you use taxes. In Germany (where I live) we have a speculation tax on property, for example: If you (as a private individual) sell a property less than 10 years after you have acquired it, any profit from that sale is taxed as income. After the 10-year cut-off you don't have to tax it at all.
The US tax code already does this by differentiating tax treatment between short- and long-term capital gains, although you might argue that the time required to qualify as long-term (1 year) is too short.
