Allah shows His creation a way to discover better means and approach of work, when and as need arises, by which they can increase the means of subsistence.
At present the global aggregate supply of many agricultural and manufactured goods is greater than global aggregate demand. Producers are competing for selling their goods.
Even if there is scarcity of goods in some part of the world then it is the result of the unjust economic system and because of the inhuman and irrational practices in the field of trade like, monopoly in production and distribution of goods, dumping surplus production in oceans to maintain price etc.
Even at the Micro level we find many people, whose income and resources are so great that they can fulfill their wants with a portion of their income.
Likewise, there are also those who cannot even meet the necessities of life with all their incomes. So the correct view here is that, there is no scarcity of resources but Allah distributes them in due measure.
Surat Al-Ĥijr (The Rocky Tract) – سورة الحجر
عِندَنَا خَزَائِنُهُ وَمَا نُنَزِّلُهُ إِلَّا بِقَدَرٍ مَّعْلُومٍ
There is not a thing but with Us are its treasures, but We send it down only in due measures. | QS 15:21
