US recession and immigration

It's not a big secret anymore that USA is facing a difficult economic crisis. It might very well be the biggest recession US has faced in a very long time. The effects of a recession is evident world over. Stock markets world over plummeted on Monday as a result. President Bush already sprung in action and has announced greater tax refunds this tax season with a hope that people will spend more and help stabilize the economy. What's causing the recession; whether it's the rising home mortgage prices, foreclosures or the war in Iraq, I won't go into those details, as I'm no economist. But there's a different side of this debate which interests me. The unemployment rate is at its all time high of about 5%, which is quoted as a cause of the ongoing recession. Some blogs and news pieces talk about lowering the rate of immigration and creating more jobs for American people. The theory is that the immigrants consume most of the jobs available in the industry. The jobs vacated by the so called immigration reform shall be awarded to the US citizens. This argument according to me lacks a serious consideration. The "legal" immigrants in US on H1-B and other visa categories constitute a huge spending force. These are the people who earn decent wages, have house and car mortgages and assume a greater spending power. Merely by taking such a work force away from the industry will not fill in the job vaccumm. It will very well push US into further recession as the retail businesses will see a significant drop in sales. Many online consumer websites will simply run out of business. As long as I'm missing a crucial point in the plan of curbing "legal" immigration and using that to boost the US economy, I don't see it helping the current or any form of future recession. I think it's high time that people realize that immigration is a reality which they cannot ignore. Immigration helps build the US economy and does not ruin it as claimed by many.
