Less competition. Curbside items that disappeared in a couple of hours are now up for grabs for days or even weeks. Also, there are a lot more active postings for scrap in the free section of craigslist - and less competition for scrap at garage sales.
Less theft. There are fewer metal thefts being reported in the news. This brings less attention to the business; see the above point. Also, there is less chance of your accumulated scrap being stolen.
More opportunity. When the market gets tough, the weak links of the chain drop out first. Closing scrap businesses mean opportunity for you to expand your own. Also, many local businesses/neighborhoods have or will lose their local "scrap guy" and you can take over.
