If the overall tax rate is more than 50% and the market and the prices on that market are the same for everybody, then it is guaranteed that the State Apparatus has superiority over all parties at that population. In those market conditions the over 50% overall tax rate makes sure that "the people" WILL NEVER HAVE AUTONOMY. This is the case in 2017 Estonia, with the small sliver of hope that the State, Toompea, is not capable of buying some goods and services that are available to the private sector.
In the case of the United States the National Debt is a means to reduce the overall tax burden and therefore gives more power back to the people of the United States. The U.S. State has to pay interests of that debt, which is money that the U.S. State can not spend on buying anything else. Given that the U.S. State has the most powerful army of the land, if not the whole planet, the U.S. State can say that they will never pay back their loan, they just "confiscate" the loaned money for "national interests", except when the U.S. State is forced to "behave" to get a new loan from the private sector. That is the reason, why there is an everlasting need to "increase the debt limit". New debt is essentially new loan and the private sector will not provide it, if the U.S. "confiscates" the previously loaned money. At the same time, the Soviet Union communism demonstrated that "nationalization" leads to the situation, where nobody has any resources, not even the private sector, which means that the U.S. State is unable to apply a full "nationalization"/"confiscation" or it will end up totally bankrupt like the Soviet Union did. At best the U.S. State can raise the overall tax rate to some level less than 100%. The banksters are smart enough to know that the U.S. State will never pay back its loan, because the U.S. State lacks the means for paying it back or even if it "paid back" the loan, it would have to do it in nonmonetary assets, probably in land usage rights.
The everlasting interest from previous loans("debt sealing increases") can be the source of money for the banksters for giving new loans("debt limit increase") to the U.S. State. At some point the U.S. State interest payments are greater than the money that the U.S. State receives with the new loan, the "debt limit increase", and the banksters can be "generous" and at their discretion temporarily decrease the required interest rate or "defer" interest payment requests. At that point the banksters actually control the amount of money that the U.S. State is able to spend, id est at that point the banksters control the de facto overall tax rate of the U.S. State.

Update on 2017_09_26. Since I intend to avoid working in the gigantic hierarchy of a super-mafia, it is important for me to take to account the parasitism rate that the "public sector" imposes on the "private sector". As it turns out, there's a table that lists the parasitism levels of different regions (archival copy). For the record, I'm not saying that there does not exist any tasks that should be handled communally, but I do say that it should be voluntarily funded slick, well automated, "non-profit" teams that should handle it, not the mega-hierarchy. I find it quite stunning that in many places "in average" 2 humans from "private sector" have to provide for a whole family of one "public sector" member and that's in addition of paying for the "pensions", healthcare, living expenses, education of their own children and elderly. The overall robbing rate, "tax rate", of ~80%(income "tax" + value-added "tax" + social "security" "tax" + real estate "tax" + etc.) certainly is in line with that observation. Interestingly, the Japan has nasty robbing rates(archival copy) despite having only about one "public sector" person per 9 "private sector" humans. That is to say, in Japan the ripoff is extra nasty and favors the super-mafia elite or they have huge supermafia grants back to the "private sector".
Some analysts urge Abe to tackle fiscal consolidation while the economy is in good shape given that Japan is saddled with the industrial world’s heaviest debt burden at more than twice the size of its economy.
That suggests that a lot of the Japanese "tax" money ends up at the disposal of the Japanese banksters, which might explain a high wealth inequality, except that due to 55% inheritance tax(archival copy) the Japan does not have the super-rich class and has the nickname of "The World's largest Communist Country". As Japanese megacorporations are able to accumulate money, the de facto rulers of the Japan are the CEO-s of the Japanese megacorporations. Supposedly the Japanese rich use the Australia as a "tax paradise". The Western Australia seems to be the liberal region of the Ausralia(archival copy)
