You can definitely do bad things to earn money. But a doctor, an engineer, etc, would've already contributed to the common good even if they buy a tenth car that sits in their garage. So simply buying a tenth car that sits in your garage (and employs the people building the car) isn't in itself a bad thing or an indication that you're not contributing to the common good.
In a free society, someone can spend their money on an extra toy if they want. Nothing wrong with that. It's a strange expectation to impose on others this notion of "spending only on the common good." It's not black and white what the common good is, and that is why an educated free market is a good proxy or mechanism for figuring that out.
