This has been a major topic of discussion in tax circles for decades, the vast majority of Americans do not benefit from deductions and the federal government's direct knowledge of your income is essentially identical to your own (because of mandatory reporting from employers, banks & other financial service entities).
Specific deductions are written by and for high income individuals, and supported by lobbying from the tax industry which wouldn't exist without them, but they're not used by the vast majority of Americans, especially with raised SALT limits and doubled standard deduction.
