The sustainability of national finances is certainly an important issue for a country's development. These aggregate perceptions change the public sector of the nation and the safety of citizens' lives. Therefore, a significant focus on broadly improving financial research can be a significant issue. In addition, this activity may be organized in connection with applicable higher education programs. On the other hand, the understanding of financial management of governments in different countries are treated differently. This is becoming an increasingly important condition that broadly discussion does not directly benefit the overall development of financial education in recent years. One of the possible ways to deal with personal finances in various economic conditions may be a change in the attitude towards knowledge financing among top management in universities. Young people can be supported by financial education programs that are clearly included in their underground or postgraduate courses. A proper management of education programs can help improve student learning experiences and economic well-being. In addition, training based on transparent public administration reliably fosters patriots of the country and people's intolerance for non-transparent activities of public servants.

This concept of tax burden can encourage every citizen to be responsible for the activities of government employees and for the transparency of the budget planning process. Improving government revenues is indeed a complicated procedure. Because the same concept of taxes is used as in fixed costs for the public sector, when a person does not directly receive anything but additional payments for most public sector services. Thus, the confusion of economical terms is fairly constant, that again demonstrates a need for public finance literacy in all finance areas. Definitely it is a serious programme for scientists. One of the problems is regarding a realization of the country's tax burden. The official average tax burden is usually more than thirty percent from the Lithuania's nominal gross domestic product in recent years. On the other hand an average tax burden for a private person is usually more than forty percent of the average nominal labour related income. Nevertheless, political leaders and experts suggest the need to increase the accumulated tax burden in Lithuania. However, there may be a fundamental error in the fact that social insurance contributions and compulsory medical insurance contributions to funds are not counted in the tax burden of individuals and legal entities. Fortunately, last year's budget already considers social benefits as part of tax revenues. Unfortunately, in the continuity of the fiscal policy of Lithuania i...
