That's ideology. Specifically, an Adam Smith style ideology.
You can very well make money without improving human life in exchange.
Heck, you make tons of money without improving human life. Like being an arms dealer. Or an African warlord. Or a crack dealer. Or a huge money seeking corporation selling sugar water. Or the very same way Belgium made tons of money for a small elite by royally fucking over tens of millions of people in Africa.
The reverse is also true: "you can improve the human life without making any money". The same way Ghandi or MLK improved human life without selling anything or being involved in any commercial enterprise.
