How can tax system strengthen the social contract?

According to the Larousse dictionary, a tax is a "deduction made by authority and on a definitive basis from the resources or property of individuals or communities, and paid in money to meet the expenses of the general interest of the State or local authorities".

Yes, taxation can mobilize the resources needed to run the State and make public investments.
Nevertheless, its missions go further: taxation influences the decisions of economic players. It is a public policy instrument that can promote social justice, in response to structural or cyclical imbalances. It can also be a vector for citizen participation, and a condition for acceptance of the legitimacy of institutions.

In other words, paying taxes means accepting the social contract and giving ourselves the means to live together.

If, as we have said, taxation plays a special role in the construction of society, is a low tax burden systematically synonymous with a weakened social contract?
What implications do these figures have for living together in countries that collect less?
Is the politico-institutional instability characterized by several coups d'état in the sub-region, indirectly, a manifestation of the difficulties experienced by countries in proposing a healthy and fair social contract?
Should the effectiveness of a tax policy be judged solely by the amount of revenue raised?

In other words:

How can we introduce a tax system that meets the challenges of financing the State's needs, while at the same time creating a social bond that enhances social cohesion and confidence in institutions?
