Quote from Ghost of Cutten:
60/40 is clearly special pleading by futures traders, there is no justification for favouring futures over securities profits. To avoid unfairly taxing quarterly rollover, have a provision for carrying forward gains as unrealised capital gains if rolled in the same contract to a future month.
Simplest is a flat tax on all realised economic gains - income, dividends, capital gains, 'dealing' income, wages etc. There is no reason why one form of economic gain should be taxed more or less than any other.
You can't argue for a fairer political and tax system, if you try special pleading for your own interests when they come under the magnifying glass. That makes you no better than unions, big business corporate welfare, lobbyists, and horse-trading pork barrel politicians.
