The population is spiraling out of control. There aren't enough jobs in the capitalist West. The unemployed will rise up and redistribute the wealth.
The world will go back to farming, hunting, gathering. Cities will crumble in the uprising leading to tribes of people. There will be technology, but it will be irreparable and as soon as they stop working, nobody left will know how to build or repair it.
The millionaires and above will be torn to shreds by mobs. Their children will be struck from the gene pool and scorched earth will be all that remains where their homes once stood.
The new world order will see communism rise again while capitalism is washed away from society.
