Classic moving of the goalposts IMO. 2015 was the last year I could get reliable data for. Wait time? What standards are you basing your comments on and what countries are you comparing the USA to? By any reasonable standard, the US is still very pro-immigration and pro-entrepreneur.
The key phrase there is "in the EU or Canada." But the point of the parent comment is that the USA isn't like those places and that there is such a thing as "American exceptionalism" in terms of having more entrepreneurs attracted enough to a culture of innovation to apply for visas.
