Incentives lag
Was reading an article written about incentives by Steven Levitt( Freakonomics fame) . He says a lot of people enter very risky and sometimes even dangerous professions because they believe in making the same / equivalent money which the previous generation has made. Cockaine drug dealing profession is such a dangerous profession that foot soldiers have an annual death rate of 7% ( 0.5% is the annual death rate of people who fight Iraq war ).
