Did you know that the most charitable people support the fewest charities? Rubbish, you say? No, it isn't.
The point is that people who do not spend their money on something, preferring to keep the money, leave the things they haven't bought to some other people. So the world gains from those people. So, if there is more supply (because miser people don't spend their money on the goods) with demand staying the same, the price will go down, so more people will be able to afford it.
Points from the above.
1. People don't spend their money and yet demand stays the same. Why will price fall?
2. if demand falls why will there be more supply, not less?
3. How can it be charitable NOT to support charities?
