This might work for someone who does not mind this or who has a place to stay while earning less than 1k USD a month for years, but it certainly did not work for me and I choose min wage jobs and self learning instead. Self learners are considered unemployable in Germany, but it gets one a fair chance in the UK or Ireland.
Can you give some specifics?
Europe truely is the "old world", with London being the only place where startups have a somewhat realistic chance of getting funded on reasonable terms, however entry level developer salaries are still poverty level in London for the first 3 years or so, as there are more candidates than jobs, unlike in the US.
All the entry jobs are filled by H1b, and most the non entry jobs as well.
Worked as a consultant/contractor in the Bay Area for ~3 years and GTFO. I made over 100 but less than 150 with 15 years experience.
And standard java dev work seem to start about 50k or thats what the Guardian was offering
