A further definition of terms
In January, I wrote Definition of terms which defined kleptocracy, looting, crony capitalism, propaganda and ideology. Here are four more terms relevant to today:
To the economist embezzlement is the most interesting of crimes. Alone among the various forms of larceny it has a time parameter. Weeks, months or years may elapse between the commission of the crime and its discovery. (This is a period, incidentally, when the embezzler has his gain and the man who has been embezzled, oddly enough, feels no loss. There is a net increase in psychic wealth.) At any given time there exists an inventory of undiscovered embezzlement in – or more precisely not in – the country’s business and banks. This inventory – it should perhaps be called the bezzle – amounts at any moment to many millions of dollars. It also varies in size with the business cycle. In good times people are relaxed, trusting, and money is plentiful. But even though money is plentiful, there are always many people who need more. Under these circumstances the rate of embezzlement grows, the rate of discovery falls off, and the bezzle increases rapidly. In depression all this is reversed. Money is watched with a narrow, suspicious eye. The man who handles it is assumed to be dishonest until he proves himself otherwise. Audits are penetrating and meticulous. Commercial morality is enormously improved. The bezzle shrinks.
Rent seeking as defined in Wikipedia:
In economics, rent seeking occurs when an individual, organization or firm seeks to earn income by capturing economic rent through manipulation or exploitation of the economic environment, rather than by earning profits through economic transactions and the production of added wealth.
Most studies of rent seeking focus on efforts to capture special monopoly privileges, such as government regulation of free enterprise competition, though the term itself is derived from the far older and more established practice of appropriating a portion of production by gaining ownership or control of land.
Deception, beguilement, deceit, bluff, mystification, and subterfuge are acts to propagate beliefs that are not true, or not the whole truth (as in half-truths or omission). Deception can involve dissimulation, propaganda, sleight of hand. It can employ distraction, camouflage or concealment. There is also self-deception.
Deception is a major relational transgression that often leads to feelings of betrayal and distrust between relational partners. Deception violates relational rules and is considered to be a negative violation of expectations. Most people expect friends, relational partners, and even strangers to be truthful most of the time. If people expected most conversations to be untruthful, talking and communicating with others would simply be unproductive and too difficult. On a given day, it is likely that most human beings will either deceive or be deceived by another person.
In the broadest sense, a fraud is an intentional deception made for personal gain or to damage another individual; the related adjective is fraudulent. The specific legal definition varies by legal jurisdiction. Fraud is a crime, and also a civil law violation. Defrauding people or entities of money or valuables is a common purpose of fraud, but there have also been fraudulent "discoveries", e.g. in science, to gain prestige rather than immediate monetary gain.
