Nhưng bọn vỉa không đóng góp 25% GDP của Mexico, đúng không?
Bọn "own-account workers, self-employed professionals, farmers, peasant agricultural workers, artisan, persons in microbusiness-- helpers and family members without a formal employment contract who work either at the dwelling or outside of it" nó không đến nỗi ít và ăn hại chứ?
Bọn street vendors có cả hội chợ giời, mỗi tuần họp một phiên bán nông sản và đồ thủ công nữa, bọn đấy bán trên phố đi bộ và bãi trống với hàng rong xe đẩy thì chả phải là vỉa. Vỉa chỉ chiếm một phần của bọn này thôi. Ví dụ:
Vendors selling from stalls may be organized into a number of formats:
- tianguis and mobile markets (mercados sobre ruedas): These markets take place in a designated place on certain days of the week, with a fixed schedule and supervised by a city inspector for compliance with weights and measurements. These markets are part of the strategy for the supply and distribution of food staples to the city.[9]
- Concentrations: areas of vendors selling from stalls, not officially organized, specializing in certain types of products, such as imported illegal merchandise or fayuca, especially electronics, in Tepito, or auto parts, tools, clothing, etc.[9] Although in many cases those selling from stalls are not truly itinerant (ambulante, in Spanish) - they are still referred to as ambulantes. Concentrations of stalls are also found at metro station entrances, near hospital entrances etc.
- Bazaars (plazas comerciales), where vendors of a certain "theme" (stationery) are housed; originally these were organized to accommodate vendors formerly selling on the street
- Individual or small groups of stalls on any given city sidewalk.
