Is it normal friend from england thinks everyone is rich in america

I'm 30, he's 25.

My friend who lives in England works in computer science. In England he makes £34,000 or $40,000 USD. His rent cost per month is £335 or $400 usd.

He wants to move to the US because he says he'll be rich and he believes everyone is rich here and argues poverty is a choice in the US because he says all our salaries are so high you can "live like kings and queens on any job".

There's a US company in Boston Massachusetts he wants to work at he would start at $60k at the highest earning is around $75k after several years. He keeps saying he's gonna be rich on that. I told him the US is expensive and he doesn't believe me. I met him while he did a volunteer travel project during the summer a few years ago. He only ever vacationed here.

Another thing he also doesn't understand is vacation days. The US is the only developed country with no mandatory 5+ weeks vacation a year.

In the UK by law you get 5-6 weeks paid vacation a year at any job from day one and he says he's going to spend a few weeks off to visit his family in England and a few weeks off to travel to a few countries like he already does. He showed me the job description and how it says "2 weeks(10 days) paid vacation after 1 year and 3 weeks paid vacation after 5 years" and he keeps saying he's going to just "take off 5 weeks like he always does and negotiate with them because he's not waiting 5 years for 3 weeks" and doesn't understand that unfortunately the US is strict on vacation

He also wants to buy a car and a dog the first month he moves to Boston. Is it normal?
