The public finance system is based on small contributions of millions of Ukrainians. In fact, common Ukrainians, not industrial giants or oligarchs, maintain financially huge state apparatus, cover state procurements and pay social assistance bills. Unfortunately, the chain "my money → taxes → government spending" is not that obvious for wide audience. Only private entrepreneurs recognize this fact bringing taxes to state treasury by their own. However, unless taxes common employees and consumers pay, government would lose two-thirds of budget revenues.
