The U.S. government's total revenue is estimated to be $3.863 trillion or $11,777 for every single person (including children) living in the United States for FY 2021. Note, that is only Federal taxes and does not include state and local taxes (sales tax, property tax, state income tax, etc.). State taxes add another more than $1 trillion to that total. I do not believe that includes local taxes (property taxes, local sales taxes, etc.). They don't need to tax anybody more. The amount of taxes collected is already absurd.
While you can certainly construe any government spending as corporate welfare, i think there is a difference between, for example, paying the company with the best proposal for a needed road repair and throwing money at a company in the hopes that they will do something better or because they donated to your campaign.
