Observation # 1 .. People who do .. do more ... people who do less ... diminish further ...
example ... if someone works more ... they get more and more work and are squeezed further ... but someone who does less work (intentionally or unintentionally) ... keeps on having the plate empty ...
another example ... in Pakistan ... more tax is squeezed out from people who already pay a lot of taxes ... but who evade tax ... still stay untouched ...
any more examples???
