Depends on how early in the transition you lose your job and how long the transition is.

I think the transition could be anywhere between 5-20 years. Depending on how efficient and proactive a government is.

White collar jobs, except those at the very top of each field, will lose their jobs first. Or atleast start to make less.

Given this, you should have 5-20x your yearly expenses saved. Wealth in currency or assets may not be stable either. So really your only hope is that the government gets it's shit together
