As silly as it is to say that government jobs don't add value to the economy - and it is silly to make a broad generalization about all government jobs ...
... jobs that do not create value relative to their costs by definition do not add value.
Not all jobs are the same.
If we decided to dedicate $5 trillion to building statues of our political leaders, that has much less value than dedicating $5 trillion to research for nanotechnology, neural networks, biotechnology, genomics, etc., which make our lives better.
I cannot disagree with that. However badly spent, virtually all domestic spending funnels right back into the economy. Even unemployment benefits and welfare. virtually every dime of that is spent in the economy.
the most valuless govt jobs are the purely political ones. Such as the presidents political advisor, etc.
Certain types of spending increase the velocity of money. We can also think of some types of government spending as insurance, such as social security or welfare, whereby the risks of poverty and the attendant ills are spread throughout the economy, at least up to a point where it discourages productive behavior.
However, those types of programs are design to induce a certain type of behavior. If resources are funneled from productive sectors to unproductive sectors, that destroys wealth.
I understand what you are saying, but the welath winds up in someones pocket.
Food Stamps puts how many billions into the grocery and food production chain each year?
Medicare and medicaid how much into the health care industry and pharma industry?
It is a suck up situation on the wealth I agree and there is problems with helping to create a more class dividied society. But we need more soloutions to work on those issues.
That suckup wealth flow also does cereate some jobs up the chain.
Not a simple problem with a simple soloution.
