@TizerorFizz As it happens I haven’t flown for 6 years, have an electric car and don’t use gas or oil to heat my home.
These choices unfortunately aren’t available to all as they are often pricey upfront even if they have reduced running costs. Again society can choose how to support transition to a green economy. And I’ve met plenty of plumbers and builders working on installing green technology.
I’m not any more perfect than anyone else but do believe that society as a whole has choices as to how wealth is generated and distributed. Many Individuals can also make choices about who they work for and how they generate and spend their wealth but overall the regulatory frameworks society & government sets are critical.
As to charities - yes they are often dependent on philanthropic giving. The charities I’m involved with do consider carefully who they accept funds from. It’s tough and complex and there are few binary choices.
Life is complex - but getting back to the thread being a teacher in my view remains a highly good use of a good university degree. Doesn’t mean being in finance is bad, nor is being a lawyer but let’s not put bright graduates off public service roles.
