Problem is what the Japanese have done hasn't solved the problem. The Japanese have tried everything. Honda and Toyota are firing the parts cannons at expensive robots, which don't really help. They started tackling the problem in the 1930s, when they introduced radio programming aimed at keeping elders more active (and less of a burden on the state). 90 years on, they are still tackling the problem. You've based that statement entirely on prejudice, with no consideration what's going on in Spain. But you are nothing if not predictable. Faced with a policy, which really as FA to do with you (unless your real name is Juanito) that could bring around a million people into the formal economy, your first assumption is "one million benefit claimants." That says more about your assumptions than Spain's economy. Spain has one of Europe's largest black economies; 24% of GDP, employing about, guess for it, a million people. A huge proportion of undocumented migrants are already working—in agriculture, hospitality, construction, care and other sectors. Regularisation means they're paying income tax and social security instead of working off the books. It also suggests you know remarkably little about Spain's welfare system, where many benefits depend on contribution records and others are relatively limited. Legal status is not a magic ticket to lifelong benefits. Not everything is like how you remembered it when on the dole and claiming the social. Your posts follow a familiar pattern: if immigrants are involved, you leap to the most negative interpretation, regardless of the economics, resulting in a combination of racialised assumptions and a poor grasp of how the Spanish labour market actually works. A million more registered workers and taxpayers is a far more plausible outcome than your fantasy of a million people suddenly living on benefits. One million new minimum wage regularised workers generates 6 billion Euros in payroll benefits back to the Spanish treasury. Currently Spain spends about 20 million Euros deporting illegals. Spain also spends abut 5 million Euros of a voluntary repatriation and training scheme; those deported migrants will get training and support setting up a business back home. Its a numbers game, many of those businesses may fail, but some won't. The Euro goes a lot further there than home funding essentially defence and security companies create an oppressive informer atmosphere, because the Spanish version of you is at home pissing himself with worry about all these migrants.
