Gonna sound coldhearted.
If we expect that no changes will occur in the economy from a new policy, then no change to the economy will happen with the policy change. If you want substantial positive change made, some existing positions will be eliminated and others will be created. Yeah, some people will pass through the unemployment zone during the transition time. If that is to be avoided at all costs, then the applied changes will be small or so ineffective as to not be a change. Change often sucks, but is necessary to make lasting improvement.
For 30 years plus we have been enjoying cheap products from china and have built a healthy import and transport system related to that. If we move to reduce trade imbalance and encourage domestic production, that vast import/transport system will change along with it. Has to. We cant build more of the stuff we need domestically and still need all that import infrastructure.
Too big to fail is bullshit. Chevy should have imploded and resulted in a series of smaller, smarter car makers along with a bunch of banks, investment companies and other poorly structured/managed enterprises that the government propped up over time.
