If China is helping its domestic industries charge an artificially low price for solar panels and other environmental goods then China is violating international trade rules that it agreed to when it became a member of the World Trade Organization.
In a finite world this means that the per capita share of the world's goods must steadily decrease.
There is one rule for the industrialist and that is: Make the best quality of goods possible at the lowest cost possible paying the highest wages possible.
I think it has other roots has to do in part with a general anxiety in contemporary life... nuclear bombs inequality of possibility and chance inequality of goods allotted to us a kind of general racist unjust attitude that is pervasive.
By far the greatest part of those goods which are the objects of desire are procured by labour and they may be multiplied not in one country alone but in many almost without any assignable limit if we are disposed to bestow the labour necessary to obtain them.
You can either invade a country or leave them alone and trade with them. When goods cross borders armies don't.
The accumulation of skill and science which has been directed to diminish the difficulty of producing manufactured goods has not been beneficial to that country alone in which it is concentrated distant kingdoms have participated in its advantages.
This avidity alone of acquiring goods and possessions for ourselves and our nearest friends is insatiable perpetual universal and directly destructive of society.
All the best have something in common a regard for reality an agreement to its primacy over the imagination.
