By alone, you mean with literally no one else.
...in which case, $500,000 is meaningless anyway. I could create a mud pie from the dirt in my backyard and say it's worth $500,000. And with no one else around, it's worth whatever I say it's worth because I'm not able to trade it.
Goods only have value in terms of what two trading partners agree on. The whole nature of prices is that they fluctuate according to supply and demand, and that is determined by groups of people who value things differently. If you are truly alone, $500,000 might as well by $0.05, or $5,000,000.
A socialized system? You mean the system that capitalism has created by which everyone, working in their own interest and of their own free will, is inadvertently serving their fellow citizens?
If that's a socialized system, then capitalism has produced the socialist paradise far better than socialism ever did, without a massive bureaucratic state and without the millions slaughtered because they couldn't be re-educated about what's good for them.
