No I disagree with you, when the price of oil goes high, it has a ripple effect on the economy, this ripple effect affects productivity, it affects transportation, gives a shockwave to the economy because most times government were not prepared for it as fiscal policies might not be on ground to curtail it. So if tell people to increase their income, you are literally telling the government not to tackle the issue head on.
Everyone would have to devise different means to overcome the challenges brought by this war. Some governments are responsible that they have began to roll out policies which would help citizens suffer less from the situation at hand. Welfare packages like subsidies, increased pay, and others are already in place.
But when you live in a country with an irresponsible government which careless about the sufferings of the masses, you would have to come up with strategies to overcome this problem. In such countries, people would have to seek alternative sources of income because the government doesn't care.
Even if you are fortunate enough to live in a country with a responsible government that has implemented policies to support its citizen during this difficult time. You also shouldnt be complacent because nobody know when this war will end and how long your government can continue to provide support.
Conflict in the Middle East and soaring energy prices are beyond the control of most governments. We should find solution ourselves instead of relying entirely on the government, because if the situation worsens and becomes beyond their capabilities. They will abandon us too.
