Fewer competitors also means fewer organizations to service for vendors. This has a huge long-term impact on the economy and local job markets as it means fewer firms being formed.
That's a really good point. If you are a vendor, you can sell to mom and pops, grocery stores, Walmart, Amazon, Costco, etc. Once mom and pops are gone, you are limited to who you can sell to. When that happens, the people you can sell too have a lot more leverage against you.
In terms of vendors, consolidation is like a black hole. The more consolidation, the bigger the black hole and the more vendors crushed by the gravity.
