I think that every country has transparency rules to provide information to its citizens about how their tax revenues are used, for what purposes, and so on. Even those who act on behalf of the state and work for the state are also subject to tax. This system is considered the best way to run a country. However, there are gaps in various sectors. For example, when the government increases the amount of income tax deductions, it is not accompanied by an increase in salaries. On the other hand, business people are always looking for ways to avoid paying normal taxes because the amount they have to pay is quite large.
Therefore, in my opinion, the best way to measure whether a country is running well after demanding that its citizens behave tax-compliantly is to look at the level of welfare of its people. The fewer gaps there are, the better the country is managed. Of course there are many other indicators related to this, but one thing is certain, only a few countries exempt their citizens from the obligation to pay taxes.
If we judge whether a country is advanced or not, it can be seen from taxation itself, depending on how it is managed, as we know, movable and immovable goods are definitely taxed, and it all goes back to being used for the welfare of the people themselves, even though many certain individuals take advantage of this tax, because difficult to eradicate because their cunning is not something that can be avoided for all of that, with the state enforcing the law to the maximum it is much better for the future to create progress for the country.
