Is immigration the only solution for economic recovery? https://www.facebook.com/truenorthcentre/videos/2700882830155388/UzpfSTEwMDAwNDUxMDg3OTQwMjoxNTU2OTgxNzMxMTI4ODQx/?fref=pymk_jewel An old man with a white beard named God - god knows where he came from!,  created Adam and then Eve from Adam, they say, and told them go multiply.  And that's one religion.  Another religion, which does not call itself a religion, started a few centuries ago, saying: (1) it's all about money, getting rich is the ultimate goal, (2) the planet is (should be) divided into Nation-States and each nation-state must only be concerned about increasing its own wealth.  Adam Smith could be considered [one of] the Prophet of this new religion with his book "An Inquiry into the Wealth of the Nations", without the mantel of the name of "Prophet".  The mixture of these two "religions", both of them encouraging population increase, gave way to the kind of conversation based on that question: "Is immigration the only solution for economic recovery?"  Actually, we do not need economic recovery, on the contrary,  we need happiness, no stress, no pollution. We need love.   Our present economic system, worldwide, is absurd and based on the acceptance of pure selfishness, hypocrisy, lies, corruption, competition and conflicts, depleting and destroying natural resources, altering the truth, immense pollution threatening our life on Earth, focusing on short term and neglecting the long term consequences of the actions of nearly 8 billion human species.  We need to put an end to the nonsense. So, for a moment, let's stop immigration (as an economic policy) and let us start reflecting on how to change things on our planet, and becoming the savior, here in this second-largest country on Earth with only 35 million people, where we really can.
