I disagree with many statements, but I want to focus on two:
> why do free market systems produce by far the greatest standard of living as compared to any other system
What other system do you mean? I don't see two systems to choose from. Every wealthy nation and most poor ones have a 'free market' system with some social welfare programs. The question is what degree of social welfare do we want to provide?
> The debt piled up faking prosperity under the welfare state system has begun to come due
In fact Western economies grew enormously in the last 40 years. The U.S.'s recent debt and economic problems are because of reckless governance:
When Bill Clinton left office the government was running a surplus and the economy was growing. Under the Bush administration, the Republicans (and the blame falls heavily on them this time, there's no point in being falsely even-handed):
* Cut revenue (taxes) significantly
* Greatly increased costs unnecessarily by invading Iraq
* Greatly increased costs unnecessarily by failing to regulate the financial sector, resulting in the worst economic catastrophe since WWII. This greatly impacted revenue (reduced economic activity reduces tax receipts) and expenses (increasing demand for social welfare, and bailing out critical industries).
* Malpractice in governance, attempting even to default on the credit of the United States to score a political point!
Balancing the budget with excellent economic performance and social welfare policies was and is possible. We did it under Clinton. If you greatly both cut revenue and increase costs, and conduct malpractice in governance, then yes you will have a lot of debt and other problems.
