A lot of things to cover, so I'll try to go in order.
1) Comparing graphs you can see that during the same time period of Mame's graph, the spending/debt skyrockets while the revenue and economic production continually goes down. This should be firm enough illustration to make you think at least: "Hey, maybe we ought to try another approach, yeah?"
Yes, in your graph I see tax revenue decreasing. So are you saying that should increase? Because all the candidates say they wouldn't support any type of revenue increase. It's all about spending cuts, which dems have agreed to. I also see in your other graph that federal outlays, which i'm guessing means spending and GDP both increase. I still feel like I'm missing your argument.
2) You assume that we need to continue the spending in order to make up for America's lack of. You need to contemplate the reason Americans aren't spending: they're broke. Why? Debt. Yes the housing bubble is the originating factor in this. Businesses lost money when the bubble burst, people lost their jobs and then had to incur large debts just to support their families. You have to remember, in order for the government to spend money they must first take it away from the American people. Why is it logical to take the extra spending money from the American people and push them further behind on their bills? Seems counter productive to me. I mean, why not cut taxes for middle and low class Americans and increase their net wealth, thus freeing up more money to spend on the market.
People are broke because stocks crashed and they no longer have any savings. Yes, the housing market crash, coupled with the fact that Bush used up all our surplus started this. Which brings me back to the point that all of this started before Obama. So why is the other side trying to pin everything on him? I agree, cut taxes for the middle and lower class. No one's saying tax them anymore. Just close the loopholes that allow big businesses and oil companies to line their pockets while laying off workers. If you're getting tax breaks, you need to hire. That's the only justification I can see for it. Trickle Down does not work, we've seen that first hand. But Reps are on a one-track stance. Which is why I won't be voting for them. That and they're hypocrites.
3) My point with the levees is to illustrate how we have conditioned our own "necessities" by sticking the governmental hand where it didn't belong. We are creating our own problems and making things worse. Furthermore, imagine if our government sold every dam or levee to the private sector. They would have profit potential in building technologies (i.e. hydroelectric power stations), add in the factor that the private citizen will now have recourse against these companies if they fail to maintain the dams or levees and cause property damage. Much greater motivation to keep the properties in better shape than our government has.
You assume the private sector will listen to the people. Greed nullifies that. Case in point, insurance companies. People complain about rising premiums and being denied coverage, but do the companies care? Not one bit. But conservatives want to reverse health care reform and throw poor people back to the wolves. If they're poor and get denied coverage or just can't afford it, fuck em, let them die right? No one cares about their fellow American anymore.
4) Bridges hold the same motive. A complete free market could enterprise the idea of private sector ownership with toll booths and the likes. It would be coupled with cutting the gas taxes and the multi-billion budget commitment to infrastructure development that so far has been failing miserably. Just an idea.
So you want a toll booth on every bridge then? That would be a traffic nightmare.
5) Should a college degree that costs $100k+ that promises an income of $30k per year if your lucky be affordable? Isn't the premise of a college degree to show excel and greater knowledge than your counterparts being destroyed by having a 100% of the population (Obama's goal) obtain college degrees further forcing more debt and need for greater education just to prove that you know more and thus are more qualified for the job? As a fiscal conservative myself, I can think of a thousand things to cut before education. War on Iraq/Afghanistan, oil/big business subsidies and loopholes, foreign aide, and much more.
Just because you go to college doesn't make you equally qualified for a job. There are still slackers out there, and the over-achievers will be rewarded. The idea is that everyone should have the OPTION to go to college. No one's forcing you to, but you should be able to if you desire. You say as a fiscal conservative you can think of other places to cut, but that's not what happens. I see it continuously. The first thing that gets cut is education. Are you saying only the rich should be able to go to college? The idea is to get a degree to better your living situation and to better be able to provide for the family you'll have one day. I agree on the things you said to cut before education though, 100%. Hell, I'd elect you over the republican candidates that are running.
edit: I just wanted to add on to #4: The famous 35W Bridge (one that collapsed in Minnesota) carried a price tag of $234 million. With the surrounding twin cities carrying a population of 2,849,567. 160,000 people work in downtown Minneapolis on a daily basis. This means that for the 160,000 workers a daily pass would cost $0.02 (at a price of 1 penny per pass) each bringing in $3,200 per day, or $1,168,000 per year. This is not including the other 2,689,567 residents in the area as well as truck drivers and visiting commuters. The price tag for the individual 160,000 workers would only be $7.30 per year.
Keep in mind, the bridge is expected to last 100 years. So with just the 160,000 workers at a constant rate would bring in $116,800,000 over the course of the 100 years. This would leave a deficit of $117,200,000, meaning you would just need to double the traffic to meet your bottom line. Either that, or increase your price a couple pennies per pass. A lot cheaper than paying the road taxes.
