How we can beat weeds

A method occured to me the other day about how we could actually win the battle against weeds (and other invasive species) if we really wanted to.  All we have to do is restructure our economy, so that instead of being built to serve humans, the economy is focused on serving nature.  Then IPM would be a major industry, employing tens of thousands of people in the Denver area alone, and instead of a few small weed crews watching in frustration as weeds take over even as they battle valiantly to stem the tide, we'd see weeds steadily cut back, until, a few generations from now, they wouldn't be a problem at all.
