What are the pointless jobs you're referring to?
They're everywhere. We could have let GM die. We could abandon all tariffs on imports. Any time a policymaker uses "job creation" as a selling point for a policy initiative, that means jobs that exist for the purpose of providing people with incomes.
Even the Fed has "full employment" as part of its dual mandate. The private financial sector funds small businesses that probably shouldn't exist. We still have local farms producing food when large-scale farming is far more efficient. Now that's fine if it's your hobby and that's how you want to spend your time, but we actually subsidize farming.
