You say this as if Trump will also not be in control of both sides of Congress. All it takes to make this a department of the government is a vote in Congress.
And most of the members of congress (all of the house, 1/3 of the senate)will be up for election in 2 years. Let’s see if they are up for cutting social security and medicare when they have to face the voters just two years later.
Let’s break this down. Payments on the debt (10% of budget) are already off the table. SS, Health Insurance (Medicare, Medicaid, ACA, etc) and defense represent about 58% of the budget. If we eliminate everything else, we are going after things like welfare, the VA, and veterans benefits, as well as subsidies to a variety of businesses. Bottom line, even if there wasn’t an economic impact, there will be some very pissed-off powerful constituents.
At the end of the day, this whole process shows that Musk and Ramaswamy are clowns.
