A good taxation policy avoids penalising productivity and taxes 'unproductive' profits.

CGT is an example of this insofar as it taxes - as politicalcompass.org so eloquently puts it - "people who simply manipulate money and contribute nothing to their society"

Taxation should be levied, generally, against unproductive profits. This has a two-fold effect of both dis-incentivising unproductive spending (e.g. what one might call "hoarding" or "banking") and incentivising genuine productivity.
