Let's say I have a relative from another country, a good hard worker, and I want/need his expertise. He stays at my house, buys his own stuff, and mentions that he might want to become "legal". I advise against it because I'm an anarchist I don't see the point in him paying federal income tax, and prefer to pay him under the table according to what he and I negotiate via bilateral contract.
Oh, and I gave him a super comfy bed just to sweeten the deal.
To you that's a crime, and the tax payer will have to foot the bill for 3 hots and a cot for me for who knows how long. Not counting the cost to maintain the overburdened court and prison system - for a victimless crime.
Here's what I say to you: Stuff it.
