None of this is necessary in Capitalist countries. There are no barricades in place to keep people from leaving. These detractors claim capitalism leads to greed. They portray businessmen as only caring about profits. Tax revenues would plummet, starvation, and homelessness would follow, leading to chaos and revolution.
True capitalists are entrepreneurial in spirit and philosophy.
They have created businesses that employ the majority of Americans and that provide services the public truly wants and desires. They know if they produce quality products or services, the profits will follow. And if their businesses are profitable, more opportunity will be created for others. The wealthy people and businesses that rely on the government creating laws and regulations to assure their profits are not capitalists. They are protectionists.
