> Most people can and if you can’t then the government pays for it.
For now.
> The relative ease with which most people can get another job is also nice.
This seems unemphathetic. Even just for the tech industry, thousands of engineers have found it difficult to find new work after the layoffs of the previous years. Please do not extrapolate your experience of the ease of finding new work towards every other American.
> It is an economy that is structured under the assumption that people will move between jobs and minimizes the friction in doing so.
No. Even if you look at it from a process perspective, true minimized friction is when other countries goverments automatically deduct and manage your taxes when you move jobs, manage retirement funds and have socialized healthcare to reduce the stress and uncertainty during unemployment. You claim that "at-will" minimizes friction is a joke compared to those.
