I've never had to live in poverty but I've never been rich either. I am content just to have enough for my needs. Any surplus money or goods I am happy to give away. I don't sell of possessions that I no longer need, I donate them to charity or pass them on to someone who can use them whether I know that person or not.
It is my belief that a society where people have sufficient resources to live a fulfilling life is the ideal. Taxation is the mechanism for ensuring that this can happen. While not endorsing Marxism, I do like the slogan "From each according to his ability, to each according to his needs".
The way I interpret that slogan is people whose income is way more than they need, and the taxes that they are legally obliged to pay, should be directed toward lifting up the people who are struggling to thrive in our society.
Two problems arise. Human nature is inherently selfish. The rich, but not only the rich, want to expand their wealth and cannot see why they owe anyone else a share in their fortune. They minimise their tax obligations legally. The poor live desperate lives and may seek solace in alcohol, gambling and petty crimes. They cannot afford higher education, decent housing and health care unless the government provides for them. Here's the rub - these and other social benefits require taxes to be levied which is what the Marxist slogan is all about.
