Yes its true all aala afsars involve in corruption so it will very difficult to finish Anna's jobs.
Removing corruption is 'our' job and not Anna's. We can hit at corruption only by understanding the causes. main cause is inherent greed in society that is obvious from the custom of dowry. when you demand money even for your son's marriage, there should be no surprise if you demand money as a govt employee. Secondly, our social system is expensive. You incur heavy expenses on birth, marriage and death. such expenses need extra income that the way of corruption provides. apart from social system, our political system encourages corruption. You need heavy expenses to fight elections. The party tickets are auctioned. The MP or MLA elected on such party ticket has to indulge in corruption for recovering the money paid for buying party ticket and the expenses incurred in contesting elections. These MPs and MLAs can indulge in corruption only with help of bureaucrats. Thus whole system gets corrupt.
The remedy is that 'really honest and sincere' persons enter active politics and work to make things better. This cannot be done by staying out of active politics and merely sitting on hunger strike at jantar mantar.
