Hardly. Even in developed western countries, being laid off can hurt families and communities.
When there are a lot of tech companies and the industry is doing well economically, and you can easily relocate or work remotely, then it's less of a worry. You can find another job with less difficulty.
But if you work in another sector like manufacturing, it can be devastating. Especially when a significant portion of the community work in that company or industry. There are large swaths of the US and UK where industrial jobs have disappeared and once prosperous areas have become impoverished in the past 40-50 years.
> We have normalised firing of people.
That's what happens in societies when the majority of people work for a corporation. The corporations are motivated by profit and will lay off hundreds or thousands of people or abandon a community if it saves money.

Many of these "developed" countries have embraced the austerity gospel. There isn't much of a safety net as the was or could be.
I don't know about the "developed" countries where people have social security,
