I'm not a translator, nor have I much to do with translating, but I'd like narrate an anecdote, from personal experience:
I used to earn my money doing trade fair construction as freelancer, charging, at the time, about DM35 an hour, which was on the low side, but bearable.
then, the Wall fell, and suddenly the trade fair construction market (which required no formal training, no qualifications of any kind, was flooded with East German and East European workers looking for jobs in West Germany.
These poor unfortunates lived in caravans, ate 'Graubrot', drank Buttermilch, and charged about DM15 an hour.
It took roughly 3 months for, imo, about one third of the professional trade fair constructors to change their professions - none of us could match those prices - dumping pure.
The irony of the story comes now: about two years later I got calls from all my former clients, begging (not too strong a term here, btw) me to take on contracts. The nub: the guys who put us out of business were really busy, really dedicated, but had no idea of modern construction methods and materials, had no idea of service, customer relations, and their continuous, forced low prices meant they had to make all sorts of short-cuts to get the job done.
in short: pay peanuts, get monkeys
