Unpopular because it's so flagrantly ignorant. How much do you know about the "egregious" expenditures by rank-and-file federal employees just doing their jobs?

USA government spending as a percent of GDP is on the lower side of developed nations (high 30s depending on the source). Our peers are Luxembourg and Norway, and we’re well below France and Germany. Granted that we are one of the few developed nations that don’t provide universal healthcare which biases us lower.

While I’d share your concerns about fiscal sustainability, we’re an outlier on tax receipts not spending.

It's unpopular because it's incorrect. This isn't fiscal "restraint", this is a spanner thrown into the federal government with the intention to cause dysfunction. When the government is no longer able to meet the needs of the people because it has been intentionally kneecapped, the billionaires who made this choice will push to privatize the affected services instead.

And in doing so, they will take the value and experience that was built up in our federal institutions over generations and throw it away to enrich themselves.
