Keynesian economics don't work. You can't create something from nothing. If 1 dollar in infrastructure spending gives you $1.50 in return, why stop at 700 billion? How about 100 trillion in infrastructure spending?
1930's make work programs, amongst other things, turned a run of the mill recession into the great depression.
Now if you really wanted to create a true analogy, go get a loan every month, and use a portion to pay off the previous month's debt. How long do you think you could do that? There's a difference between short term borrowing, and running constant debt.
How does that strategy work for places like Argentina, Venezuela, and Greece? History is littered with failed States that tried that as a long term strategy. You can't just create wealth by fiat.
When you spend more than you make, do you force your employer to give you a raise to cover the difference? No, you spend less. Its called living within your means, and you have zero understanding of what that means. Just because the government can alter its means to support its lifestyle does not mean that its a good idea.
Actually they made no ruling to the constitutionality of section 215. What they did determine is that the Obama Administration was exercising authority not granted to it by section 215, therefor the practice of bulk collection was ruled illegal.
"A three year joint study (3) with Forest Engineering Research Institute of Canada (FERIC) and
the Alberta Newsprint Company (ANC) investigated the potential for using a B-Train
combination equipped with central tire inflation (CTI). Three road surfaces were studied; native
earth block-entry, lightly gravelled forest access roads and asphaltic-concrete highways. The
native earth thawing block-entry road was constructed as a 100m X 75m two lane oval track.
The track had a low section, a level section and a 6% grade. The outer lane was used for “high”
tire inflation pressure and the inner lane was used for “low” tire pressure conditions. The single
test vehicle operated on one lane at high tire pressure until the road failed - defined as when ruts
of 10 cm in depth occurred. It then travelled on the other lane at the low tire pressure setting until
the surface failed. During the test program, the tire inflation pressure settings were as follows;
high-pressure condition was set to 100 psi; low pressure ranged from 34 to 39 psi. The test
vehicle was a 7-axle unit having a GVW’s of 56.5 tonnes.
The tests found that tires inflated to the high pressure (normal) settings rutted the road surface approximately nine times faster than when inflated to the low pressure settings. This extreme result is due in part to the very weak structural condition of the road. It is estimated that the road had a CBR of 3, which is typical of weak, thawing conditions. In general, initial rut development decreased by 77% when low tire pressures were used."
So far, you're the only one that gets it. Literally the only one that understands the relationship between tire pressure, contact patch, and vehicle weight.
Actually, contact area is determined by the weight of the vehicle and the tire pressure. What do you think would happen if you had a 2000 lb vehicle on tires inflated to 10,000 psi? You would have a contact patch totaling.2 square inches divided among the four tires. What kind of damage do you think 2000 lbs on.2 square inches would do?
To say that vehicle weight is the only thing that matters is flat out wrong. It is dependent on the substrate and surface pavement composition. they both matter, but seeing as pavement fatigue is the primary source of road failure, and tire pressure contributes most to pavement fatigue, tire pressure has a large effect on road wear.

Roads are handouts? Everyone can use a road. I can't use so and so's Obamaphone or internet connection.

That's because Barack Obama is incapable of rational thought, and the bills he endorses reflect that.

If by "extended" you really meant "repealed", you would be correct.
And yet, I subscribe to 60Mbps cable service, and I actually get 60Mbps cable service. No caps, throttling, or other shenanigans.
Bingo.
...that we have found another excellent use for embryonic stem cells.

If the unicycle had higher tire pressure than the dumptruck, in some situations yes it could.
Looking at that page, tell me, how many PSI does a single axle weighing 18,000lbs exert on the road?
Weight of vehicle / tire pressure = contact area. It's linear, and has no relationship to recommended tire pressure.
By the way, have you ever used snowshoes? Or perhaps you've worn stiletto heels on a lawn after a rain.
So far, you're the only one that gets it. Literally the only one that understands the relationship between tire pressure, contact patch, and vehicle weight.
It depends on how heavy the angel is, and how small the point of the needle is. But yes, potentially an angel standing on a pin will damage a road.
Have you ever ridden a bike with narrow wheels on a freshly paved road? I have. It made a rut.
Ok. Elementary physics lesson.
The force exhibited upon the road by a vehicle is called pressure. Weight divided by contact area equals pressure.
Gravity is an attractive force exerted by all matter. The mass of the matter determines the force exerted. Weight is a measurement of that force.
Sure, in one failure mode. There are several failure modes that you are ignoring.
Yes, because big rigs often have 90 psi tire pressure.
