Steve's barking at why the budget is like buying a house

There are many economist who I have the utmost respect for who make the claim that the budget can't be compared to what happens in a house budget. Now there are many people who have a degree (maybe even a PHD) in economics whom I have the most contempt fore that claim that we can compare the US budget with a household budget. In my bizarro world, I like to compare the US budget to buying and maintaining a house.
When the average person buys a house they put a percentage down and get a mortgage to pay the rest. In our budget process we have tax receipts to cover our down payment and we borrow the rest, just like one does with a mortgage. In hard economic times generally the interest on the mortgage is low, same is true with government bonds. Now in the in the past wages have gone up in the average American household to more then cover the interest rate and the principle (this is important). Because of the growth of income taxes if stayed the same would more then cover what we borrowed in the past. We have constantly cut taxes there by cutting our chances to pay back our debt. This is kind of like what the average American home owner is up,against now, income is going down and it's harder to keep up the mortgage payments. Now some of us our lucky we have money in the bank which we can use to pay the mortgage, or even better yet we have a rich uncle Fed, I mean Fred who we can borrow from, and because he has us in his will paying back that loan isn't a top priority. Those of us who aren't so lucky can possibly get a second mortgage. Now isn't that what our government does.
Now there are certain things that owning a home needs to be done. The boiler might brake down,
The roof can come off during a wind storm, termites, water damage. The smart homeowner takes care of these problems right away, buy using the surplus income, borrowing from Uncle Fred, or getting a second or third mortgage. Shouldn't our government think the same way.
Now I understand that there are many a person who believes that the government borrows too much, my question to them is, do they tell that to themselves not to buy that summer home with a mortgage and or a new car on time payments?
