No billionaire is self-made. There is a lot of help, including work by employees and collaborators, help from government. Like your shipping company has the government-sponsored interstate to thank for getting goods around at a cheap cost. Your online company has the government-sponsored Internet to thank for your websites success. Paying more in taxes has led to large corporations being more prosperous, the United States experienced its best economic periods during eras of "high taxes." The notion that low taxes breeds innovation and more prosperity is completely, false, it is not supported by the data. When everyone pays their fair share in taxes, it helps stabilize the middle class and provides assistance to the poor.
When corporations are reaping record profits, while filling out government assistance applications for their employees, they're stealing from you. Just make them pay their fair share in taxes, then we won't have this problem.
