Seriously, I'm going to need someone to tell me why this can't work.
You get some capital together, and you go buy some bulldozers, a wrecking ball, a couple of backloaders (I went on some auction sites...I'm stunned how cheap some of that heavy equipment can be), find yourself a demolitions expert...and then you open up a destruction company.
But you're not the one doing the destruction.
No, it's people like me doing the destruction. Or you. Or anyone.
I read stories like this one - http://www.freep.com/article/20120415/NEWS01/304150016/For-many-kids-in-Detroit-school-zones-are-danger-zones - about how many abandoned, dangerous buildings there are near schools, and there's a problem.
And then I realize that there are a lot of people with a lot of pent up stress and frustration. And I see an opportunity...
