Show of Hands

No. The govt is the facilitator and the referee. Its role is to keep the competition active and fair. Not to pick and unfairly advantage winners as it all too often does, particularly in the defense, equipment/transportation, energy, and healthcare markets. It may try and apply a limited amount of protectionism to ensure imported products aren't produced abroad using slave labor, thus somewhat levelling the playing field for the domestic workforce and preserving the social fabric from radically different systems abroad. But this must be done thoughtfully and constantly adapted to recent evolutions. That is not what Trump's tariffs are doing, beyond all appearances and despite all the demagogic messaging.

This question has so many variables

Nothing guarantees that and nothing can. But capital is responsible for enabling the greatest opportunity people have ever had for living a comfortable life.

The only guarantee is taxes and death

We don’t have a totally free market system now. Government intervention has led to higher prices and lower wages.

“Responsible for guaranteeing?” Sounds like a legal guardianship. LoL. Regardless, nothing can guarantee lifelong employment.

Communism doesn’t guarantee that either.

No. There are no guarantees no matter what the economic system is.

No, but there are flaws to a completely free market.

Nothing is a “guarantee”.

No, but I would submit that as long as there is a market for something (goods & services), the opportunity for employment will exist.

No. That requires protectionist policies which is what the government is needed for.

No

No, but it helps.

There is no such thing as guaranteed employment and wage protection. Slavery guarantees employment, but not wages.
