American Recovery and Reinvestment Act

As I was driving home, I saw a sign that said "funded by the american recovery and reinvestment act". The above sign is actually in a different state, but it is the exact same one.
I was curious so decided to research it.

At the website for the American recovery reinvestment act, one can find what its all about.

• Save and create more than 3.5 million jobs over the next two years;
• Take a big step toward computerizing Americans’ health records, reducing medical errors, and saving billions in health care costs;
• Revive the renewable energy industry and provide the capital over the next three years to eventually double domestic renewable energy capacity;
• Undertake the largest weatherization program in history by modernizing 75 percent of federal building space and more than one million homes;
• Increase college affordability for seven million students by funding the shortfall in Pell Grants, increasing the maximum award level by $500, and providing a new higher education tax cut to nearly four million students;
• As part of the $150 billion investment in new infrastructure, enact the largest increase in funding of our nation’s roads, bridges, and mass transit systems since the creation of the national highway system in the 1950s;
• Provide an $800 Making Work Pay tax credit for 129 million working households, and cut taxes for the families of millions of children through an expansion of the Child Tax Credit;
• Require unprecedented levels of transparency, oversight, and accountability.

That all sounds like a pretty swell idea to me. However, I wonder if the funding might fall short before projects are finished. Will that money come out of our taxes in that event? I just hope that doesn't happen.

This seems like a good way to help the economy by giving more people jobs and saving money where we were over spending before. They predict that in the next to years, 396,000 jobs will be saved/ created.

so this picture shows where all the money goes. I pretty much understand it all, except for "protecting the vulnerable". What is that? I looked all over that page with no explanation because it doesn't have an asterisk over it. I am always suspicious of things with such ambiguous titles. But I shall investigate farther later.

This was something I thought was cool: You can zoom in on your town and see exactly which corporations are getting money, and exactly how much.

Well it all looks alright to me but I still have questions.

I suppose we shall see how this plays out.
