Justifiable government jobs are those that serve a proper function of government: universal rights to protection of life, liberty and property. Since these functions cannot be fulfilled by the private sector, government must provide jobs in performance of these functions. The only necessary government jobs, therefore, are: (1) military jobs, since the entire country must be protected to preserve its existence; (2) law enforcement and disaster prevention/management jobs, since the country must be protected from crime and disaster to preserve property rights; (3) judges, since the judiciary must be impartial; (4) legislators, since legislators are supposed to serve their constituents and are answerable to them.
Because government jobs are jobs that are unnecessary and/or useless and/or overpaid, and because money for those unnecessary/useless/overpaid jobs must come from somewhere, government jobs destroy real jobs. In essence, growth of government jobs creates unhappier customers and less profits, poverty and poor service.
Full employment is not an economic goal. It is a byproduct of utopian economic growth. When full employment becomes an economic goal rather than a byproduct, everyone lives in poverty, unhappily employed by the government -- as in Cuba or the USSR.
The private sector has never destroyed a real job. The private sector has made certain real jobs obsolete, lowered wages for certain real jobs, and even outsourced real jobs -- but because the private sector is answerable to the needs of the market, every demand must be supplied by a real job. The only way to destroy a real job is to destroy the ability for suppliers of real jobs to meet demand for real jobs. And the only mechanism capable of destroying that ability is government, which can tax suppliers of real jobs into oblivion on behalf of government jobs, regulate suppliers to prevent them from meeting demand, and shut down suppliers to punish political adversaries.
I know it's difficult for you to follow that logic, Democrats, because you've been taught for so long that a job is a job is a job -- that digging a useless hole in Montana is the same as becoming a private sector pediatrician. It's time to wake up. For too long, your simplemindedness has destroyed the same jobs you purport to care about.
If you insist on foisting your flawed, fatuous economic principles on the nation, we will have no choice but to apply private sector principles to your jobs. In other words, we'll dump you on the street without hesitation. That's certainly the best way to restore profits and serve customers.
