In America we have economic freedom. Meaning we have the capability to chose our own jobs, start our own businesses etc. This is because we have mixed market economy. This is good since people in america can make their own decisions allowing for a more free country.
In Cuba we also have economic freedom. The problem is money. with little to no money to go around its hard to manage in Cuba,and prices of goods and services are also very high making it even harder. The only positives are that we are free to sell and trade so people help each other.
One problem people in america face is income. Often the income someone earns is based more on the ability to negotiate during a job interview than some "work hard, earn more formula. It may not be as serious as other problems but its still a problem.
In Cuba some people cant even afford to buy food and many people go hungry. Some people have to make the choice to eat or buy clothing for that month. This is because of a trade embargo that was set in place resulting in inflation, less goods to go around and not much money either.
Overall the quality of life is pretty good in America. The US ranks at the top in housing and ranks above average in income and wealth, health status, jobs , earnings education and skills.
Cuba is characterized by reasonably priced housing but besides that quality of life in Cuba can be bad considering the low incomes and small amounts of goods and services people barely manage.
