What does this even mean?
Please give a specific, concrete explanation of how and why it's easier for someone to "create something" (create what?) in the USA than in the EU or Canada.
> Canada actually has a very strict immigration politics compared to the US then sure.
And yet apparently accepts around three times as many new immigrants per year than the USA, as a percentage of population.
> The tough people were the ones who endured what it meant to live in the US in the beginning. There weren't tough when they went on a boat but they soon became just as their children and their children.
So is the USA the land of opportunity or the land of greater hardship and toughness?
People don't typically leave the country they know and love for another land, unless enduring hardship already. OTOH, while they may believe (at least in part due to propaganda[1]) another land will provide greater opportunity, that doesn't mean it does.
