First off, trickle up has one of the same flaws that trickle down has.  Not all of the money will be spent.   Second the initial money has to come from somewhere.  It has also been proven that businesses will cut new hires and reduce hours to compensate for the extra expense.  Either that or they will go out of business.   How do cover the expenses until businesses can recover some of that extra cost?  Even the state legislature was complaining about extra expenses because of labor.
