In 1911, he wrote
The Passing of the Idle Rich. In that book, at the time of the election U.S. President
Harrison, Martin, commenting on the power of American plutocrats to influence the political and economic
status quo of the nation, wrote: It matters not one iota what political party is in power or what President holds the reins of office. We are not politicians or public thinkers; we are the rich; we own America; we got it, God knows how, but we intend to keep it if we can by throwing all the tremendous weight of our support, our influence, our money, our political connections, our purchased Senators, our hungry Congressmen, our public-speaking demagogues into the scale against any legislature, any political platform, any presidential campaign that threatens the integrity of our estate. Martin's writings often criticized the extravagances of the indolent or newly rich members of American Society and preached that "...where idleness and extravagance creep in decay begins. Nations as well as individuals have to be reminded of the dangers of these evils and they must be faced". He also hosted an annual Christmas dinner for the homeless on the
Lower East Side. Martin received a large sum of money on the death of his brother, Bradley Martin. It was Sands intention that both of their collections be kept together and housed in London. ==Personal life==
