J, your argument is not valid. Mom and Pop stores don't grow because they don't want to, a small company that WANTS to grow will find, or create, a niche and fill it.
Want some examples of small company owners that wanted to grow ?
How about Henry Ford, Rockefeller, Potterfield, or Sam Walton ?
Your talk about "the community" losing the income of 5or 6 employees is flawed as well, since the "community" gains the dividends payed to thousands, even 10's of thousands, of investors, like every single member of this forum who has a 401K, IRA, or other retirement account.
The stocks owned by banks ?
Where do you think they get the money to pay interest on your savings account ?
It is simply a fact of nature that many people start business', some grow huge like Debeer's, most only last the life time of the founder.
Are you going to blame Ford because buggy whip makers can't find jobs ?
The law of business is the same as any other survival situation, if you don't adapt to the changing circumstances you will fail.
Lets look at another aspect, at one time the big bitch was that K Mart was killing small business, they were even forcing out companies like Rich's, now Wal - Mart is cutting into their business, so what ?
It is an evolutionary process that has, and will continue to function as long as people engage in trade. Railroads, Steel, oil, communications, all have existed in a near monopoly form at one time or another, all have been changed by competition with some one who developed a different product, process or sales model. It's never going to change unless you want to adapt the Soviet style "planned economy" advocated by BO and the rest of the Socialists.
Russia showed us where that leads, stagnation and decline.
