I don't know what "all other" factors could mean - since we don't know what factors have already been mentioned - but I assume that the pay and work conditions would be the same (those could be the "all other" here and the difference is Italy vs Germany/Belgium).

The payment, working conditions and work stability are likely to be better in Germany or Belgium, so if one can find a job, there, one is more likely to go to Germany or Belgium
