The US isn't laissez-faire. Most proponents of free-markets would point to the current crises and relate them to the central bankers. Interest rates have been centrally planned rather than floating on the market. Banking regulations drive banks to hold treasuries. When new treasuries are issued at a higher rate of interest, the rate of discount for lower (near zero interest) t-bills increases, putting bank balance sheets out of whack.
As flawed as the US economy is, at least there is still something resembling a market price for basics like a loaf of bread. Yes, you can claim that the USSR wasn't the socialist ideal, however moving further from that claimed ideal results in a more productive economy. To the extent that the west is increasingly centrally planned, it has become relatively less productive.
Things aren't binary though. No one is saying the US isn't "real capitalism", they are just specifying what type of capitalism it is. But that's a very different than saying there's no true Scotsman. There's a reason one is a fallacy and the other isn't.
this is so false i have a hard time believing you actually think this. that said, i strongly encourage you to put your money where your mouth is and invest accordingly!
