Actually altruism makes fortunes for the rich. It allows them to get tax relief and the kudos from making large donations to charities and funding "foundations" and scholarships does more for their coffers than the equivalent advertising spend.
Additionally
genuine altruists, the volunteers who give their time and the citizens who donate their wages are often doing work that
should be done by the State allowing governments to reduce the taxes of the rich because they have offloaded the responsibilities on to charities.
No I disagree with your opinion. Autism is real and not a conspiracy or a fantasy. Neither is altruism the enemy of capitalism, it is it's facilitator.
If governments did the things that altruists do via charities - cancer research, feeding and sheltering the homeless, helping addicts recover, farming programmes in 3rd world countries, outreach to autistic people and a million other activities, the tax burden on the rich would be much higher.
One of our most prominent (and loathesome) capitalist, right wing politicians in the UK even described charity run food banks as "rather uplifting"
