Family Trusts are often testamentary trusts, bequeathed at death from tax-paid money.  There is no tax dodge here.  Instead of bequeathing money into the hands of minors and infants, a Trust is formed where ALL income each year must be distributed to beneficiaries by a responsible person - income remaining inside the trust is taxed at a the highest rate.  Trust tax rules have recently changed to become much less attractive from a tax perspective.  Sheer is a hypocrite on this one.  And, anyone can form such trusts on death.

Farmers and businesspeople who have large pools of capital captured in companies can do an estate freeze and transfer the newco to family members.  There are may ways to skin a cat.  

The idea that the proposed changes will cause every fat cat to suddenly freeze in their steps and take a big tax hit is ridiculous.  Anyone smart enough to form a personal corporation to sprinkle wealth is smart enough to find many new ways forward that will work under proposed laws.
