Most American’s can’t afford to invest in the stock market to any meaningful degree, and certainly not in any way that would offset the proven wage stagnation that has been going on form decades. Therefore your first point is false and all economic analysis concludes that the share of prosperity for most Americans has been declining.

Apple certainly does pay their fair share of taxes, but this doesn’t do anything to change the economic structure.

Your facts are correct, but irrelevant.

Apple does not pay their fair share - http://fortune.com/2018/01/18/apple-bonuses-money-us-350-bil...

Despite the innuendo, that piece doesn’t actually show that.

Apple exists under the same tax regime as every other company and pays what is due. You can certainly argue for increasing taxes on various corporate activities, but to claim that Apple doesn’t pay it’s share is false.

The point is, paying their legally mandated share is not necessarily paying their fair share

By what standard, other than tax law, can the fair amount of tax be determined?

By some assumed standard of morality. "Fair" tax can never be determined by tax law - only "legal" can be determined that way.

There exists a fair tax: the user fee. Pay for what you use. (But then we are still reduced to bargaining over what is a fair price).

Insurance is also a form of fair tax, when premiums are based on claim history and objective risk factors, and the market is reasonably competitive.

Are any companies paying their ‘fair share’ then?

Can you show me a single example of a company paying more than it’s legally mandated share?

If not - why pick on Apple?

You can not invest living paycheck to paycheck. "Any American" can not do what you are assuming is so simple.

To invest in American companies you'd first need capital to invest. It's not like that's a birthright.

But do people feel that they pay their fair share?
