I don't think anyone is suggesting subsidizing the coal industry directly, except of course those congressmen from steel or coal producing states. The rational thing to do is to support miners directly, the ones put out of work, and provide opportunity for re-training in other industries. In a rational capitalist economy, the ideal is to let supply and demand determine where financial resources flow, whenever possible -- in some areas of the economy it is impossible, medical care for example.Then artifically subsidizing an industry that is dying out? Coal mines are going to close down on their own as we move to cleaner energy naturally so passing legislation to artificailly subsidize it is a waste of taxpayer's money. Rather then let the workers get canned and go on welfare and see icnreased poverty and crime in those areas, offer retrianing for other careers and incentivize other businesses to come into WVA.
Yes it is cheaper than just letting a couple of thousand people move on to benefits and welfare. That is much cheaper than throwing money to keep it afloat so Manchin can win another election.
However any good capitalist will suck at any teat available. That's where the role of government comes in. To protect society from capitalism's pernicious tendencies, while at the same time assuring a healthy economic environment that capitalism can flourish in. We are only in trouble when either the People are, in aggregate, uneducated, or the capitalists control government. The U.S. is in some danger of both of these threats. The way to handle this is to recognize where the threats are coming from and move to counter them. We are dependent on our Congress to do that.
