I checked teachers salaries and I think they average $40,000 pa. I hope she doesn't teach economics.
The problem here is we always want more. It never stops, especially in the richest country on the face of the Earth where no one has to fight for cooking gas, electricity, water and basic shelter. The interest rate is close to zero percent, you can buy cars and a house with almost no money in the pocket. The upward mobility is also high. But I admit, it requires base level efforts and intelligence.
All who are complaining would never would live in 3rd world countries or socialist countries where they know they would struggle just to survive for life. There is no path to progress. Life is just a struggle every day. I know because I came from one.
The teacher of economics at my graduate school in New York said in the class that.... :"Travels to lands outside the U.S. and come back and pay your taxes happily to enjoy a good life". People don't really comprehend what that means. There are people like Barbara Streisand character in the movie ... "The Way We Were".
America is not a great country for teachers. You have to find a country like Cuba. America is great for the rich and celerities. People from around the world come over to this land to get rich or famous.
No country is great for everybody. France is for great romance and wine, the Middle East is for history and fanaticism, South Asia for history and primtivity, South America for religion and crime mafia, Africa for dictators. Every land has its unique offerings.
