Why? What metrics and how do you quantify that? I'm not believing that the US is less free than Canada.
Earlier in this thread some other posters mentioned specific studies that have rated the nations. Look up these studies for the metrics they used. As an example, the USA has some of the best medical facilities in the world and cutting edge medical research but accessing medical treatment is a real problem for many USAnians primarily because of cost.
A few years ago a friend was vacationing in Florida. He likes to bicycle but he took a bad fall and had his wife drive him to a hospital ER. He was there a couple of hours and recieved prompt and professional care. They gave him an x-ray, a tetanus shot, a half dozen stitches and cleaned up his road rash. The bill was $1800.00 !!! They returned to Canada and he went in to his own doctor to have the stitches removed. The doctor commented that if an American recieved the identical treatment in a Canadian hospital ER he would have been charged about $200.00
Comparative outcomes -------- Canada / US :
per capita medical spending --- $4500 / $8500
percent of GDP ---------------------11.2 / 17.7
public share –---------------------- 70% / 48%,
doctors per 1000 -------------------- 2.4 / 2.5
nurses per 1000 ----------------------9.3 / 11.1
life expectancy ----------------------- 81 / 79
smoking rate --------------------- 15.7% / 14.8%
obesity rate -----------------------25.4% / 36.5%.
As you can readily see, Canada achieves comparable or superior outcomes at close to half the expense and every citizen regardless of status or income has equal access.
