This is true. The source listed in the article, the Center for American Progress (CAP), which is an independent, nonpartisan policy institute, claims tax cuts are primarily responsible for the recent increase in the United States debt ratio.
"The current fiscal gap—the growing debt as a percentage of the economy—stems from legislation that cut taxes, disproportionately for the very rich," wrote author Bobby Kogan.
"Tax cuts have added $10 trillion to the debt since their enactment and are responsible for 57 percent of the increase in the debt ratio since 2001," also wrote Kogan.
Although this claim is true, low taxes are not the only reason for high debt in the United States. It is a notable event that has recently triggered a large increase. Other recent factors still play a part in the debt, such as the Great Recession and the COVID-19 pandemic.
According to the U.S. Treasure Fiscal Data website, as of 2022, the U.S. has gained 20.72 trillion dollars in debt just in the past 20 years, which is almost 2/3 of the overall debt. A recent spike in total debt is shown in multiple graphs. As of this moment in time, the current debt is 31,459,270,694,014.
"Tax cuts, stimulus programs, increased government spending, and decreased tax revenue caused by widespread unemployment generally account for sharp rises in the national debt." says the site.
