Australia!

Australia is not without flaws but could be considered.
English speaking: you'd feel right at home from day one!

(Including the TV programs)
Increasingly multicultural but with a strong English/UK tradition: legal system, medicine, political system, financial system, language, government.
There are many expatriate Americans doing well here: politicians, teachers etc.
Our aircon installer recently was an American Italian with a strong NJ accent.

There are some downsides, including outrageous house/rent, electricity prices, water rates. A current housing shortage.
Some areas along the East Coast (Queensland and New South Wales) experience regular annual flooding, so don't buy real estate there, and we do drive on the left hand side!

Most of the state capitals could use more accordion technicians.

I'm sure an accordion technician could quality for residency under the "skills shortage" provision.
