Everyone knows that taxation is necessary in a modern state:【51】it, it would not be possib

le to pay the soldiers and policemen who【52】us; 【53】the workers in government offices who look after our health, our food, our water, and all【54】things that we cannot do for ourselves.【55】of taxation, we pay for things that we need【56】as much as we need somewhere to live and something to eat.

In some countries, too, there is a tax on things sold in the shops. If the most necessary things are taxed, a lot of money is collected, but the poor people suffer【67】If unnecessary things like jewels and fur coats are taxed, 【68】money is obtained, but the tax is fairer, as the【69】pay it.
