Bullshit. If tax rates remained at the Pre Reagan levels, across the board these issues would not exist.
This is a follow on to right wing "Trickle Down Economics' and series of 'tax cuts after tax cuts' and NOT the programs.

Many supported studies show that If the United States had maintained its pre-Reagan structural tax revenues, the national debt would be entirely paid off today, and the country would have a massive multi-trillion-dollar surplus to easily fund entitlements. [

The pre-Reagan era (specifically 1946 through 1980) was characterized by much higher marginal tax rates on corporations and upper-income earners. The
Brookings Institution notes that when
Ronald Reagan took office in 1981, the top marginal income tax rate was
70%. Through his landmark 1981 and 1986 tax overhauls, he slashed that top rate down to
28%, fundamentally lowering the baseline of federal revenue as a percentage of the economy. [

Multiple fiscal analyses map out this exact "what-if" scenario, focusing on the structural revenue gap and the compounding effects of subsequent tax cuts. [1, 2]

The Core Analysis: Structural Revenue Failure
The primary analysis comes from non-partisan and fiscal think tanks and macroeconomic retrospectives published by institutional managers like
J.P. Morgan Asset Management. [1, 3]
Their findings highlight a permanent shift in federal revenue relative to the Gross Domestic Product (GDP):
- The Baseline Shift: For decades before the 1980s, federal revenues regularly matched or outpaced economic growth. However, because of the sequential tax cuts started by Reagan and deepened by the George W. Bush, 2017 Trump, and 2025 Trump tax cuts, federal revenues plummeted from an historical average of roughly 19.1% of GDP down to a modern average of 16.7%. [1, 2, 3]
- The Compounding Effect: A CRFB analysis reported by Yahoo Finance notes that just the major tax cuts enacted in the 21st century alone are responsible for 37% of the total current debt. When adding the compounding interest required to service that borrowed money found that these cuts drive over 57% of the modern debt-to-GDP ratio. [, 2, 3]
- The Ultimate Conclusion: Economists from these groups calculate that "absent these tax cuts, the US national debt would be fully paid off today," leaving the federal government with a massive net surplus instead of a $40 trillion debt load. [1, 2]
