Don't worry, the kids are cool if you cash in on their inheritance

A study by the University of South Australia suggests that public resistance to inheritance and estate taxes has declined in Australia. Researchers found that two-thirds of young adults and senior Australians are in favor of taxing estates worth more than $3m, which could help address social inequalities and increase government revenue.
