The US economy has been slowing ever since WWII and the economy's of over countries has been catching up to the US. middle class wages have pretty much been stagnant for the past several decades. when you account for inflation, increases in various taxes, increases in the cost of goods and services, etc. the income the average middle income wage earner makes the same amount of money as they did back in the mid 70's but everything cost much more now.
If you go to the chart below and look at the section titled: "Personal saving as a percentage of disposable personal income"
U.S. Department of Commerce. Bureau of Economic Analysis
What this shows is basically how much money people have to save after paying for housing, energy, taxes, etc. That number has been steadily declining for decades. the US economy runs off the consumption of good and service by the middle class. since middle class wages have stayed stagnant the middle class has been getting deeper and deeper into debt to continue spending and consumption. This is where the various housing Bills, etc. come into play during the Clinton years and after. Basically the gov needed to "invent" an economy so the middle class could continue spending. But to make a long story short US citizens where using their homes as ATM's and pulling out equity at alarming alarm rates. For the most part the US in in debt and there is no real current answer to this problem. For the most part people burden with financial debt and extreme revolving debt balances are now working for the banking industry.
The society here in the US is very "Id" based..everyone wants what they want now and they don't want to wait to get it. back in the 70's you had to save 20% for a down payment as 100% financing wasn't even an option. Common sense tells you that if you can't save the money for the down payment then you can't afford to own a home. But here in the US everyone wants the big family, the big house and the new cars every couple of year and they want it now and that mentality has cost us dearly. For the most part all but those in the top 20% of wager earners in the country are fucked because everyone else spends the majority of their money on living and does not have enough savings for investment. In this day and age a person would want to save the minimum of 10% of the personal disposable income.
The US need to go back to the times when cash was king and credit was used sparingly. People need to start living below their means and not above it. We also need to move away from keynesian borrowing (when the US gov borrows money from other countries at low interest rates) and move to a fiat money system.
Another thing that goes along with the current spending habits in this country are unrealistic wage expectations. people think that they can run up big revolving debts and then pay it off with monies from "pay increases" years down the road but that's not the way it happens in reality. inflation and the increasing costs of goods & services consume the small living wage increases that some and not even all get today. for the most part if you are broke now you will be broke 10 years from now unless you eliminate current debt and not create any new debt while somehow increasing the income by a rate of at least double that of inflation.
