I don’t think I could wholeheartedly support a “help small/local business” cause. Not everybody have or need to have their own business. Who whould help the rest? Successful local business doesn’t nessesary mean better quality of life for the local people. It might, ideally, but that’s just an ideal.
I feel a bit repelled to join bunches of enterprising individuals all shouting “Buy from me!” or to be a lone one screaming or begging just like that. That’s not a right purpose of life.
People can still sell stuff and earn money along the way but the core message should be REALLY HONESTLY WHOLEHEARTEDLY people’s benefit. This cause I could join.
