"As long as you have money the US is great" even if you have money you will still have to go to the local hospital for emergency and will have to wait for specialist appointment some stupid amount of time unless you actively spend time and money donating to the hospital some serious $ so you have direct numbers of people in charge etc.
It depends on where you live. The US tends to be highly segregated by income/wealth. In the high income places they have ERs advertising to get more business because they are underutilized.
