Not sure how it is where you live, but when I pay taxes they don't go to politicians. The taxes go to health care facilities, infrastructure, education, etc. etc. Only a small percentage goes to pay politicians, and it's all in the open - we know exactly how much each of them is getting.
And are those programs where capable of delivery anything on time and on budget?
Some are, some are not, and some are before time and below budget. In other words, it varies.
