Actually you are mistaken. I do not have a "post 1980 attitude", I have the attitude that USA was built upon or pre-1908 attitude (before the Sherman act, before IRS, before Fed, before Medicare and Medicaid and SS and minimum wage and labour laws and all the departments and business regulations and income taxes, before the insane levels of inflation due to government defaulting on the gold dollar).
You shouldn't be worried about 'business practices', you should be worried about individual freedoms. Business practices in a free market deliver what the market wants. Without individual freedoms we get nothing we want at all.
