Can hedge fund managers really work to maximize their clients' profits?

We can read many from newspaper articles that talk about how hedge fund managers play strategies to maximize their own profits instead of their cilents'. This is natural but immoral. Hedge fund managers have very good incomes, especially with their "two and twenty fee" structure. With this fee structure, managers with better performances will have higher incomes; however, if there is a strategy that can increase their own wealth more than if they better manage their clients' wealth, they are more likely to go for that strategy and not to improve their clients' wealth management strategy. Therefore, if clients want their investment managers to maximize their profits, the clients have to increase their payments to match the managers' gains from maximizing their profits. Managers with more personal wealth tend to be more difficult to be satisfied, so managers who stay in the industry for longer time demand higher and higher incomes. This results the incomes in this industry increase rapidly. To maintain the income level, it is important to attract more people into this industry and increase the competitiveness. If the managers are not performing well, but still have high incomes, the firms need to hire new people and make the income level more relevant to the managers' performances.
