The only true way to avoid taxes is to not participate in any taxable activities or own any taxable assets.
The super-rich don't pay taxes because technically, they really don't own all their wealth. Their wealth is owned by trusts. H.L. Hunt, for example, died owning only a $4,000 pickup truck, despite being worth over a billion dollars.
You can use a trust to shield your assets as well, you just have to be willing to surrender ownership to a third party in a trust relationship, while still enjoying the benefits of use of the assets. While technically not in control of the assets of the trust (the trustee is) you do retain the right to replace the trustee. Because of this, your annual "list of wishes" are adhered to by trustees who wish to remain trustees.
Suze Orman, the personal finance guru, talks about irrevocable living trusts as a means to avoid death taxes. They can also be used to avoid income taxes, depending on how you structure your vocation.
For example, if you write a book, you gift the copyright or royalty rights to a trust you set up. You then plan your annual living needs into your "list of wishes" recommending the trust buy a home or lease a condo for your use, purchase a car for your use, etc.
Now, you wonder how you could do this with a regular job. Simple: be a volunteer. Trust fund babies do this all the time, they 'volunteer' with various non-profit and for-profit entities, so they earn no income. Instead, the terms of their volunteer position are that the employer will donate certain funds to your trust. If you structure your trust to have a purpose beyond supporting your own lifestyle, like shaving the whales or spreading liberty in the Free State, such that it can be classified as a charity, your ostensible employer can write off its 'donation' to your trust in its own taxes.
