I want to start a campaign againt the huge service tax charged in India?

The service tax at more than 12% literally means that every 1 rupee out of 8 rupees from a middle income man, who wants to spend or enjoy or engage in a future-building activity or sometimes invest, is robbed off. Can it be reduced? Are we getting better returns for the money taken from us. Is it the level in other advanced countries ? Can we make it somewhat as simple as 5% before next budget ?
