Take a moment to look outside of your borders. In the UK we have a mostly progressive income tax system with various tax brackets, tax free allowances up to 12k GBP, claw backs of said allowance over incomes of a certain amount, national insurance taxation, student loan repayments, etc...
The majority of UK citizens file no paperwork with HMRC (equivalent to the IRS) and never have a reason to contact HMRC.
The majority of UK citizens only interaction with HMRC is when they get a summary letter in the post at most once a year telling them that everything is fine or they over/underpaid through the automated systems. In the latter casen they either are given the money owed or told that they will have to repay what is due through what is effectively an interest free loan over the course of the next 1-2 years (can be negotiated).
The reason why this is possible is because employers report salaries to HMRC and its a deduction in their monthly payslips.
You might say its not possible to do that in the US, but ask yourself how does the IRS actually know that you have misreported/underpaid? Its because they already know exactly how much you owe because the same information has already been reported to them by the banks and your employers.
There is literately no point in tax filing for the majority of US citizen that work as an employee employer except to enable the parasitic tax filing industry to exist.
