The FBI says companies are losing thousands, if not millions of dollars, in stolen trade secrets and other valuable data when disgruntled former employees hack behind company firewalls. One problem is the increased use of the so-called “cloud” in the form of Dropbox or Google docs. That’s making it relatively easy for folks to gain access to their former jobs. And as Marketplace celebrates its 25th birthday this year, we are looking at the surprising,  sometimes delightful and sometimes destructive ways that prices have changed during that quarter century. For example, a medium capacity window air conditioner, in 80’s style faux wood paneling could be had for $300.  Factor in inflation and that’s like $575 now.  An equivalent 8000 BTU window AC unit, again Kenmore, today goes for just $219. But although the price tag is way cheaper in real terms, here’s the concern when it comes to household budgets and climate change: when something like this gets so much cheaper, it changes our behavior.
