We should be spending more not less.
It's simple. Government spending cycles through the economy and creates profits for private businesses and potential for hiring as it does so.
Cutting spending generally means losing jobs either directly or indirectly.
For example . . . . . As a person involved in higher education my salary comes from a private institution. But, many of the students that come to said institution pay their tuition through government backed loans. Nearly all private colleges are in a similar situation.
That means government money pays my salary and that of the administrative staff and maintenance. That means they can pay their bills and buy food supporting local businesses. The students come in and spend their money at local businesses too. They support textbook manufacturers, notebook and pen manufacturers and even cell phone service providers. All this private enterprise from a government program.
If the government spends MORE money on higher education that means more money flows into all of those businesses and they can hire . . . more people. Those people then can in turn spend more money in the economy stimulating other businesses.
If you cut that money, there are fewer students that can afford college, less money flowing into the system. Cut government spending anywhere else and the same thing happens. People lose jobs and less money flows into the economy.
The problem is governments are not businesses, they're not individuals. One of Government's purposes is to try and smooth out rough parts of the business cycle. Currently in the US there's very low consumer demand because so many consumers are unemployed and underemployed, they have little money to spend. Government can do something or it can sit back and twiddle it's thumbs and hope that the private sector magically invests when there is no profit to be made. Companies are currently making plenty of money by downsizing their workforce, cutting salaries by outsourcing and demanding that workers work longer hours just to stay employed. You can cut their taxes and cut spending all you like, it won't change the problem of consumer demand. In fact, it will make the problem worse and it's not very hard to see why. And you know what? If the economy doesn't grow the debt will keep getting worse no matter how much you cut because taxes will keep shrinking.
