Libya was a NATO intervention that was pushed and led by France, specifically Sarkozy's government.
Furthermore, non-intervention only meant no actual American troops in Syria, not staying out of the conflict: the US has funded, armed and trained much of the opposition from the start of the conflict, and US made and supplied anti-tank weapons are prominent in the rebels ability to counter the armoured forces of the Syrian army.
It ended marginally better because NATO's intervention decisively tipped the scales against Gaddafi's regime.
The Syrian civil war has been in a stalemate for years, and only recently has Assad's regime been making inroads due to Russia's decisive and no-holds-barred military intervention.
That's how you keep power and that's why you have such a high standard of living. You think it's because you work hard but it's not. At least not primarily.
