Paying taxes is a citizen's responsibility. The construction of our country needs the support of taxpayers, so paying taxes is our responsibility and obligation.
It is very noble that you think so and I admire it, but I guess you must be very young to really think so. The reality is that majority of people (if not all but the few most noble) pay the taxes because they have too and if they don't and get caught (what is very likely) the punishment is very severe.
