Gain at the firm level
Obviously
is not always an addition to social surplus
In fact competition among firms can work to lower social surplus if losers become a source of idled factors
And then there's zero sum games
And red ink off sets combined with spoiled
Unsold products
And and and
All about us is uneven Ness
The interplay of red and black
Surplus real social is built and wrecked
By market struggle
