You are so right and that arrogance is propelling them to power and control -- their bottom line.
Marx and Engels had to rush through their economic study and publish it, because without it and its justifications and methods there was no way to fund the incredible costs of a government with socialist goals.
They lament "income" inequality, and then cite wealth instead of income. They cite wealth, truly property in general, and then want to manage every-ones' income.
It is thievery for power, plain and simple. Get one group lusting after some others property or earnings and then have that group give them the political power to TAKE and STEAL. We all know where that ends up.
Twisted face and twisted mind...
