From a business perspective, times of adversity can be an opportunity to display true value in respective communities. Attempting to take advantage of people in cases like these always backfires sooner or later.
Unfortunately, while many people run businesses that can and do lend a hand in crisis situations, many businesses suffer heavily from lack of mutual support.
You might think some products and services have no place in all this but everyone fits in somewhere. Even if you already have a niche, times are dictating that everyone find their niche in relation to current events.
Artists give historical contributions in the form of embedded social commentary whether ambiguous or boldly stated. Producers give us the option to supply ourselves with commodities and novelties we would have to otherwise make ourselves. Distributors make products and services widely accessible for a majority of intended audiences.
Even seemingly forgotten or foreign markets make a difference in the bigger picture as one market changes in supply and demand, related marketplaces respond. For example, when gas stations decrease in supply, demand and prices go up but also the electric automotive industry experiences a positive growth as a result.
Do whatever it takes to survive; however, keep a broad perspective and stay proactive in business, community efforts and stay honest in marketing.
