We can and should judge the level of tax burden on a higher and broader platform. It depends not only on how much money the government receives, but also on what the government does after receiving the money. Not only depends on the amount of money collected by the government.
More or less, it depends on the quality or efficiency of the work after the government collects money. In other words, the level of tax burden can only be judged from the clues that fiscal revenue is related to fiscal expenditure and price is related to quality.
It is possible to draw a more comprehensive and reasonable conclusion.
As for the specific operation, it is necessary to establish a more complex economic dynamic model to effectively analyze whether the tax level is at an equilibrium point. I suggest you read articles related to the DSGE model, especially the part about taxation.
