Jobs are a by-product. Companies are not started to create jobs. They are started to make money. If people are needed to help make money in a given venture they will be hired.
If a person cannot produce at least the amount it cost to employ them then it doesn’t makes sense to hire them. In most instance the person would need to produce a surplus beyond what it costs to employ them.
Jobs are not leaving. What is leaving is the capital, ideas, entrepreneurs, inventors, etc, that need people to help them make money.
Of course once a business makes money there is the question of how much our government allows the company to keep. Suffice it to say many countries are much more hospitable than our own.
While I don’t disagree with you to a point, there has to be some rationality to all this.
If it is optimal to have tens of millions out of work, then the best situation would be to have everyone out of work.
That obviously isn’t the best situation.
We need to develop and implement policies that help business turn profits with domestic employment. If we can’t do that, we are done as a nation.
