Humans have lived on Earth for 6 million years. It was around 200 hundred years ago that the human population reached 1 billion. However, in just over 200 years the world's population has increased drastically. In your opinion, why do think this has happened? * answer for brainiest:)

well its not not rising unemployment and falling inflation.

hope this good !

i believe the answer is: returns on investments, no wages

people who belong in upper class society would most likely get there by obtaining multiple source of income, which a certain percentage of ownership for businesses. since most of them are job creator, they would most likely get their money from profit, not wages.
