Affiliate Marketing Secrets

So Spam sucks – yes.
But the only spam I get is Viagra. Are the spammers actually affiliated with Pfizer? Do they get commission for every 1000 e-mails or something?
I get that it’s a bot sending all the emails, but someone sets the bot up. Do those people get a kick back from Pfizer?
If so, isn’t there legislation prohibiting excess solicitation that would take the problem directly to Pfizer?

When President Obama was creating his stimulus package why didn’t he go the direction President Roosevelt went and pass legislation to create jobs? He could have rebuilt our infrastructure which is depleting. Doing this creates jobs and benefits the entire nation. He could have invested in clean energy and other eco-freindly things that would have also created jobs as well as cut our dependency on foreign oil and with our niche of unprecedented innovation, America could have created the next big thing which would then raise revenue and not only benefited us but the world as a whole.
Why wasn’t this done? It seems logical.
