I guess we mix up economic systems with political systems and both Marxists & Capitalists believe that over time economics trumps politics.
We live in a world where our ideas are principally formulated from the bottom up (big data) rather than from the top down (ideology).
The big contest at present is the American way vs the Chinese way and, IMO, that has still a way to go. If one considers poverty, then I guess china has the timber on the USA in that China is gradually taking the bottom quartile of its people out of poverty while the US bottom quartile is lapsing more into poverty. That is evidenced by the growth in homelessness and 44 million Yanks on food stamps.
The Middle Class is growing a flyshit in China while the Middle Class while the US middle class seems to have plataued .
The upper Classes in both countries are growing wealth at a rate of knots as evidenced by the growth of Billionaires .
Ideologically for China the wealth gap is by far a bigger issue than it is for the Yanks who still harbour that mythical "American Dream". That's why, IMO , one dare not criticise the US Billionaire Class because US RW Populists with the asses out of their pants seem to say (That is if they ever heard of WB Yeats "Thread softly or you will thread on my dreams"
But of course to criticise the Chinese CCP means a stretch in jail!
The Chinese Government simply deprived the poor of their liberty as it took up to 800 Million out of abject poverty and of course one has to seriously ask does US liberty trump US homelessness. Is one happier to be 'free" and living in poverty or 'unfree" and having a normal working class existence? (at least not homeless or on Government food handouts)
I guess if one wakes up in the morning and doesn't know where the next meal is coming from, that politics and/or ideology is not such a big issue..eh?
