This is not about prioritarisation man. Each country is looking for skilled immigrants such is Australia, US, UK or Canada. If you are not skilled you will have troubles to come there, simple as that if you will only invite low skilled, older people you will end up in a big s*** teoubles after few years as your wconomy will suffer. You will not have enough young workers to keep up paying taxes lol
also as a country you are loosing competition
each should group should have equal chances and its own immigration paths
