And there is an argument for companies to pay both a wealth and a turnover tax, appropriately scaled. This might be able to stimulate more diversity of small/medium companies, and thus negating the monoculture like markets that currently seem to arise on a per sector basis, also allowing wider ranging ideas to flourish.
The tax system in western countries generally does not seem to have kept pace with the change in what work/productivity now is, and so gives incentives to the established rather than the emerging.
A number of eastern economies seem to have worked out better regimes encouraging overall diversity of enterprise - it is a tricky balance as you don't want to remove the incentive to try, but the concentration of wealth we see is not healthy in such individualistic societies as the west has.
