How does that demonstrate moving up? If you come from wealth you are also likely to become wealthy yourself. That's the opposite of moving up. A millionaire who has 2 children and gives them a million each has just made 2 more millionaires.

Moving up requires people from lower wealth backgrounds moving up and the evidence clearly demonstrates that the US is one of the western countries where this happens the least.

The linked document is new money, as in people who weren't millionaires previously. Since we're discussing startups, where would you consider the best place to be to create a business?

>Moving up requires people from lower wealth backgrounds moving up and the evidence clearly demonstrates that the US is one of the western countries where this happens the least. 1,000,000+ people annually immigrate. Clearly it's a terrible place for your family.

No the linked document looks at two things new wealth and new millionaires. The new millionaires are not necessarily just the ones from new wealth and there is no stipulation that they are self made millionaires so my previous point holds. The US is a great country for those that start out with wealth advantages but not so great for those that start out very low.

If you want to compare immigration figures as a measure of how great a place is then lets take the EU. The EU is roughly similar to the US in terms of GDP. In 2016 there was about 2,000,000+ immigrants from outside the EU to the EU suggesting that it's a more popular destination. If however we take a more realistic measure of net migration (migration as a percentage of population) then the US is 29th on the list behind many European countries but also such noticeably desired locations such as the UAE.

Migration are not a great measure of whether a country is a great place to move up through society.

The EU is a series of countries, that's a moving goal post. Only Germany comes close to the US with immigration figures and the US is nearly triple their figures, and has ~40 million immigrants total, more than any European country not to mention that Europe as a whole is extremely racist compared to the US.

In your opinion which European country is best for startups?
