Final answer:
It is false to claim that agreement on a fair tax system is easily achieved with understanding of the four tax standards; fairness and equity in taxation are subjective, and opinions on what is fair can vary significantly.
Step-by-step explanation:
False, it is not easy to come to agreement about what is a fair tax system even when everyone understands the four standards of ability to pay, efficiency, simplicity, and benefits received. This is because the concepts of fairness and equity in taxation are inherently subjective and can vary greatly depending on individual values, political ideologies, and economic circumstances. The ability to pay principle argues that those with greater financial resources should pay more in taxes, whereas the benefit principle suggests that taxes should be paid in proportion to the benefits received from government services.
