Nice try, taxman! Nyahaha!
Taxes keep famine, war, and pestilence at bay.
Also, not paying your taxes is an easy way to ruin your life, and paying your taxes is an easy way to improve it, assuming you live in a country with a competent government.
I can't tell you how much I love not having to hike down to the river for water, or not having to smell heaps of garbage at neighbors houses because we have trucks pick it up roadside.
No one ever tries to hijack my car either, mostly due to tax-funded stable, secure society.
Taxes make life great, even if we don't spend them optimally.
edit: you only need open a history book to find out how miserable life was before
