Society as a whole over-consumes positional goods, and under-consumes non-positional goods. However, non-positional goods are not being consumed at a level of zero, so why not make money selling those? If you can make an improvement to an existing non-positional good, or come up with entirely new ones, that would also shift some consumption from positional goods to non-position ones, which would further satisfy your altruistic values.
