My best estimate is a Cr was worth about $1 in 1977. That makes it about $3 2002 USD, or 4 Euros, or 1.5J. In 1977 the minimum wage was about $2.50 an hour, or equivalent to 420 Cr/month. A newly graduated engineer made about $20,000 a year, or 1500 Cr/month
So a 1000 Cr/mo job is worth $36,000 a year in 2002. A 3000 Cr/mo job is $108,000 a year, which compares favorably with an airline pilot.
