Some people think they should not pay any tax to the state. To what extent do you agree or disagree? Some people complain that they are imposed a heavy burden with tax which reduce their disposable income. I think we should pay tax, because if there were no support from tax, society could not operate effectively. With the tax fund, the government can subsidise the public infrastructure projects, including roads, schools, and hospitals. People would be uneasy to commute if the traffic system was in an inferior efficiency. Like, a traffic congestion will make commuters spend more time and energy on the road. Another, public schools can provide children the education opportunities and allow them acquire knowledge by help of tax, which is also beneficial to the development of economy. Such public projects can seldom receive the finance from private capitals because these projects are not that profitable. Meanwhile, we should recognise that through tax, government can achieve the purpose of income redistribution. For example, in many countries, high income earners have to pay a considerable amount of tax while the needy people will get the financial aid from the state. Through imposing tax, besides, individuals' behaviours and habits are also regulated to some extent. Some people often cannot show restraint and self-discipline to change their bad habits. By tax on cigarette and tax on alcohol, those who smoking and drinking excessively are discouraged to consume these products, thereby living in a healthy lifestyle, and then impact society positively that the stress of the health care system is alleviated. On the other hand, the heavy tax burden hamper the development of the economy. People who were industrious in working or setting up a business would not as motivated as before if the tax rate was rising continuously, because a large portion of their income have to be turned over and their efforts were not considered to be paid correspondingly. The high tax rate will encourage citizens to evade tax and even migrate to the countries whose tax burden is acceptable. I am convinced that tax is the the lifeblood of the economy as the functions I described all above, though the excess tax will have an adverse influence on the economy and society.
