What are the pros and cons brought by the development of e-commerce?

The disadvantages outweigh the advantages

E-commerce destroys the entire business ecosystem, although I also like the convenience of online shopping, but there are many disadvantages of online shopping

One, it increases monopoly, so that the capital control of business, control the vitality of the national economy, continue to go on, the harm is incalculable

Two, it makes the intermediate business without ecosystems, the intermediary business. Increased redistribution of profits, building more new cycles, increasing economic vitality

Third, the damage to the local economy, can not promote the existence of a small economic circle, the same will jeopardize the economic vitality of the third-tier cities, and ultimately the third-tier cities will be even more unattractive, the talent was siphoned off by the mega-cities, the harm is enormous

Please adjust the policy in a timely manner, so as not to cause more harm
