It completely depends on your frame of reference.
After tax but before expenses I earn around £10,000 per year. This presumably places me towards the 'poor' end of the spectrum of the UK population financially speaking.
If you take the view that every human life is of equal value then you have to look at the global picture. On this metric I am in the richest 12% of the world's population.
Globally speaking I am very wealthy, in a very large part due to luck (I was born in the UK).
This is a controvertial topic, but it could well be argued that using our privileged position to accumulate more wealth for ourselves than we need to live comfortably, whilst others worldwide are suffering terribly in extreme poverty, is morally indefensible.
If you look at it purely from an opportunity and ethical position, the thing to do might be to use our privileged position to maximise our earning potential and donate all income (above that which we really need to be happy) to causes that can be proven to alleviate suffering.
This sounds quite extreme, but the interesting point is that this will have a very small negative impact on our wellbeing, and a huge life enhancing benefit on the wellbeing of others. It is also quite possible that the immense satifaction experienced from living by this philosophy will actually make you much happier than the accumulation of excess personal wealth ever can.
You can literally save the life of a child every year by donating £3000 of your annual income to someone like Against Malaria Foundation. How amazing would that feel, forever!
I'd be interested to hear your thoughts on this, it is a concept I have only recently been made aware of. Does it make sense or is it problematic and unrealistic?
One of the things I like about it is that it puts the focus on the individual to do good things rather than relying on blundering and biased politicians to act on our behalf.
If anyone is interested in the concept there is a lot more on the phiolosophy of this in the podcast I posted yesterday. Highly recommended!
