How do you feel about the administration trying to dismantle the IRS when that agency brings in over 400 times the amount it cost to operate?

The IRS operates on a relatively small budget compared to the revenue it collects. In FY 2024, the agency had a budget of approximately $12.3 billion, yet it collected over $5.1 trillion in tax revenue. That means for every $1 spent, the IRS collects over $400—a staggering return on investment. If the suggestion is to dismantle this agency, what would be the better alternative where taxpayer is given fair and equal treatment as well as being fiscally responsible since the government is currently spending on a deficit?
