1. The facts in that case would be that capitalism is designed around having consumers who can afford things by working. Welfare (including pension) depends on a large number of people funding a smaller number of people's lifestyle. Giving rights and education to women leads to a falling fertility rate which leads to an aging population. Most developed countries are at the point where they are dependent on immigration to maintain the current system - or need to make drastic changes, like letting older people starve and die, in order to survive without immigration.

2. Those who "have" money made it by relying on a society that was built with other people's money - roads, education, health, utilities, etc. It is only fair if they contribute to the continued running of that society instead of concentrating the wealth offshore and still wielding the disproportionate increase in power as a result.

Of course, it's much easier to go "REEEEEE, YOU HATE AMERICA! YOU COMMUNIST!" But bots have to be trained specifically for that, which tends to gimp their intelligence to match the intended audience.

In a perfect information world, the first question could have a factual answer. It's not asking if preserving the cultural identity is worth doing, it's asking if closing the border is necessary to do so.

Of course, people are pre-primed to read it as "should we have more or less immigration".
