Certainly however it's not a net gain for the government unless the money is being spent in a fashion which lends itself to growth e.g. if you build a road and that road leads to greater economic activity you make a net gain.
Spending money on salaries does not lead to a net gain for the government. In fact it's almost always going to be a loss to due to the nature of our economy - some of that money will be spent on exports or leave the country in some other fashion.
The arguments put forward by advocates here suggest the government can spend money arbitrarily.
Kevin is correct.
It does in fact add to the net tax figure.
Say a company pays 100K in corporation tax.
The state then uses that to pay a public sector worker. That public sector worker then pays 20K tax.
The total net tax take is now 120K
What you are you are talking about is different.
Look at it like the Irish economy. Manufacturing and selling a product internally is recycling money or moving it around.
Manufacturing and exporting a product is creating new money.
The Public Sector are the domestic market and the Private sector taxes are the imports.
