General Discussion

If he does eliminate the IRS it will be like a descent into 1834 Dickensian England. Surely these clowns know people do their jobs for money. The tax codes motivate people to comply and Congress over many decades has enacted rules, deductions, worksheets, schedules to require, motivate certain behavior. If you eliminate deductions for improvements on rental units, for example, guess what? Landlords will stop improving. Soon you'll be in quite a fix. Contractors will have far fewer jobs.

I suppose in a dictatorship it could all happen with a penstroke. Dissolve Congress, close the IRS. But yeah people, politicians, businesses would all have questions and make an uproar. And government would stop. Chaos. The FBI is finis, except for inventing crimes against Trump? Criminals would like to know.

The whole thing is unworkable. Propertied classes will act to protect their own, which should keep the system intact to a large degree. You can't remake the world
