Increasing minimum wage would definitely increase money spent throughout the economy, but I think business owners would offset that cost by creatively reducing/stagnating pay and benefits for middle-class type roles. And the resulting extra demand (without extra supply) would prob lead to higher prices for common goods/services (even more inflation), therefore compounding the issue we are discussing now. On top of that, a big chunk of the extra minimum-wage money spent (by the employees) will end up in the pockets of the richest as they "reinvest profits back into the business". IMO this is essentially transferring wealth from the middle-class to the upper-class via extra money paid to the lower-class.
