Hi,
Having spent quite a reasonable time in the US and travelled over 9000 miles through 30 states I would question a couple of points.
1. Health Care - Look at the cost of Private Health in Aus and what the Government is discussing at present
2. Food - Unbelievably cheaper in the US where there is competition not as 2 giants here.
3. Roads - Most roads are excellent, highways and off the highways. They build better roads and they have more extreme weather for the roads.
4. TV - More channels yes some pay but much more variety.
Having said the above we still are in the best country in the world but the pollies are slowly stuffing it up.
