Funny. I dont see him mentioning the Republican attitudes towards the wealth or poor at all.
But then you are probably someone who thinks that unless you support government programs that keep people dependant on government, you aren't helping the poor. Which is quite the opposite. The best thing to do for the poor is to help them through personal ministering and private charity.
The Right believes in not outsourcing our responsibility to take care of others to the government.
And if you were really concerned with Adam Smith's attitudes, you'd be looking at his Book "Theory on moral sentiments" which is a companion to the Wealth of Nations.
See Adam Smith realized that it's the hand of Divine Providence that is the Invisible Hand and to have that Hand work in the economy, the people had to follow the Lord. That seems to be ignored. But if you keep the commandments, the nation prospers. If you don't, the nation doesn't.
Hard work, Industry, cease to be idle, Be honest, Live within your means, Serve others, etc. These are all virtues the Gospel teaches and principles to a sound economy.
Problem is our nation has been decieved with the so called "Work smarter, not harder" mantra implying that going to four years of college and graduate school somehow makes you a more valuable worker. It can sometimes. Other times it doesn't do much than waste our time and keep us from actually learning how to create value in our lives.
If you are an honest person, and can develop a system to serve and add value in people's lives (The more the merrier) you will be well off. If you think solely of profits and how to squeeze money out of people, you will never succeed in the long run.
