Exes always get good jobs because employers know they're good workers. "But during these next few days, you'll discover what being an Ex is like. You see, Joe, the treatment can't possibly take all the criminal tendencies out of a man. So the treatment does the next best illustration...." take this fifty or not. Why don't you go out and get a job like everyone else?" As an answer, Joe handed her his CPA ID card. She grunted when she . He had never heard how the treatment prevented an Ex from committing a "And who'll hire a guy with criminal tendencies? You know the score. When you try to get a job, they ask to see your ID before they even tell you if there's an opening or not. If your CPA ID says you're a DCT, you're SOL and they tell you there's no openings. Oh, I've had several jobs ... jobs like all DCTs get. I've been a garbage man, locked in a prison and taxpayers' money would have supported you until useful citizen, unable to commit the smallest crime. And you've got a big hand in your dirty little mind that's going to slap it every time want to hire you for. I want you to help me commit a crime.

He smiled at her admiration. It was A civilization weary of murder, robbery, kidnapping, counterfeiting, wonderful world, Joe. A world of happy, healthy people. Except for you to do a job for me. It'll only take a few minutes." was a hero to the millions of men and women who had suppressed impulses to kill someone, beat their mates, get drunk, or kick a dog. Not only a hero, but because of the CPA Treatment, he was—when he left one of the CPA hospitals—a thoroughly honest and hard-working individual ... a man who could be trusted with any responsibility, any amount of money. And therefore, an EX (a convicted criminal who received the treatment was commonly called an Ex because he was in the strictest sense of the word an Ex-criminal) ... an Ex was always offered the best jobs. "Well," the girl said. "I'm honored. Really. But I got a date at ten. Let's get it over with.

But guys like you are a nuisance and take up my time." "I couldn't leave if I wanted to," Joe said. "I'm flat broke. Thanks to your CPA system, a DCT can't get a decent job." Hendricks reached into a pocket, withdrew several bills and extended them. "I'll loan you some money. You can sign an IOU and pay me back a little at a time." Joe waved the money away. "Listen, why don't you do me a favor? Why "Can't do it. Convicting a man of a crime he didn't commit is a "Why don't you take the free psycho treatment?

The FBI had always been a powerful organization, but under the supervision of the CPA, it was a scientific colossus and to think of kidnapping someone or to contemplate the use of narcotics was pointless. A counterfeiter's career was always short-lived: every place of business and millions of individuals had small counterfeit-detectors that could spot a fake and report it directly to the Brain. And the percentage of crimes had dwindled even more with the appearance of the robot police officers. Many a criminal in the past had gambled their aim was infallible. It was like a fantastic dream come true. Only the dream wasn't fantastic any more. With the huge atomic power plants scattered across low prices, no endeavor that required power was fantastic. The power required to operate the CPA devices cost each taxpayer an average of four dollars a year, and the invention, development and manufacture of subconscious over and over, year after year, until he knew that crime was the same as filth and that criminals were filthy things. Except men like Joe Harper. No system is perfect. Along with thousands of other DCTs, Joe refused to believe it, and when he reached apartment 204 at 2141 Orange Street, he felt as if he'd inherited a gold mine. being respected as a successful criminal, he would be ridiculed.

He'd waited a long time for this day. But now—another change in him— those people are down there because they admire what you did? They're down there waiting for you because they're curious, because they're glad the CPA caught you, and because they're glad you're an Ex. You're an ex -criminal now, and because of your treatment, you'll never be able to commit another crime as long as you live.

You can't figure out some things for yourself and I don't want you walking around the rest of your life thinking I did you a favor." Joe frowned. Few men had ever done him a favor and he had rarely employee and he doesn't live in the apartment you robbed. The CPA pays the rent for that one and he lives in another.
