Putting big boxes out of business in favor of mom-and-pops to help Social Security is like trying to put out a fire by throwing gasoline on it.
Knocking off big box stores would probably result in more minimum wage jobs net, just thanks to the lack of an economy of scale working at the retail level. Of course the vast majority of them would be worse jobs with even fewer benefits, since they'd be stores below minimum-number-of-employee thresholds for any benefits or protections the employees would actually want, and non-union to boot. Then the lack of efficient distribution and relatively high overhead would cause prices of most consumer commodities to double. Next, all those workers would demand the minimum wage (Which is all mom and pop can pay them, if that in the case of family dragooned into helping) go up to match. Finally the people already on Social Security find they can buy about half what the used to be able to buy, and demand their COLA escalate to cover the suddenly-rising cost curve of living.
Net result, some more people end up with jobs, but the overall quality of the jobs goes down, inflation goes through the roof, and Social Security is in even deeper trouble than it was already.
Brilliant plan. This DUer must be on Obama's Council of Economic Advisors.
