Don't go thinking that learning trade X or skill set Y or getting credential Z means anyone is set for life.
There are no simple fixes for the current situation where anybody's livelihood(*) can be reduced in value by automation. All the old middle-class certainties like:
- I own a house, which is an asset whose value will only go up
- I have a college degree, which guarantees me a middle-class job
- I have trade labor skills that have been valuable for many years, and will be valuable for the foreseeable future
are no longer certain.
(*) If you're lucky enough to have monetary assets of $500,000+ that you can invest conservatively, and are disciplined enough to live on only the proceeds, you're pretty safe.
