I ask this question because in my country we used to receive like two rain seasons in a year.All of a sudden the weather patterns have significantly changed and we have not received any for like three years now. If at all we get rain here it's very minimal and during different times altogether...
I think we are not supposed to forget something called life expectancy. For Instance most countries have it at early 60's. This can also affect the employment age according to me.
That's what you outlined are the major challenges of the self employment especially in the informal sector. It's very sad actually to see that you have to work even when you fell sick for you to bring some food on the table.
For me I think the government must invest more in the traditional means of economy like the farming of food crops and rearing of livestocks. With this they can guarantee food security in the nations and would be in a position to control the economy of the nation.
In my country no one cares about the covid 19 anymore. Most people ignored about getting vaccinated and they are living their lives in normalcy like any other.
