The thing is, when some prices plummet, and some services are no longer needed at all, those to whom those dollars used to go will be adversely impacted. Some, severely so.
That is also why we will never “voluntarily” do away with the federal income tax system. The sheer quantity of accountants, lawyers, government employees etc. that make their living off that system is staggering. You don’t pull rug out from under so many people without their being consequences. Severe ones.
Consider, the cost of making the energy will drop - that does NOT mean the profit margin will drop. If the cost of making electricty is 6.5 cent/KWhr and you sell it with taxes and profit included for 8.5 cent/KWhr - you have a 2 cent/KWhr profit.
Now, if cost dives to 1 cent/KWhr - you add your taxes and profit in - and we arrive at 3 cent/KWhr. Uncle Sam get’s the same amount, the utilties get their same budgeted amount. This is still a drop in your household bill of almost 66%. And finally, because the cost is lower - you may use MORE energy than you did before - so everyone’s profits still go up.
No layoffs -we still need linemen. However, the demand for coal and hydroelectric will plummet.
