The high bar is there to ensure the system satisfies the "will they contribute to our economy" criterion. Sure, that results in immigrants being more qualified and having more earning potential than the average native citizen. Nothing wrong with that. On the contrary, it means each immigrant will in average increase the country's GDP/capita. It also means the working class will be less likely to oppose immigration. Where are you from? In middle-income developing countries (Brazil, India, China, Mexico, etc), educated, middle-class people typically earn well over $1000 per month. People who earn $200 per month usually don't fulfill the other requirements in the first place.
