Listen, your country needs to pay for infrastructure some way.
That money has to find its way from your pocket to the budget, there are no miracles here.
At least with electricity bill you have option to use less electricity and pay less taxes. Would you like it to be levied on some things you can't decide to use less?
If you think your country costs too much, vote for people that promise to make the government cost less.
