The general rule is, the further left you go, the more you are supporting the agenda of the ruling class: that is, the clerisy, the bureaucrats. Supposedly subversive movements like BLM, Idle No More, Me Too, No Kings, Occupy Wall Street, are really controlled opposition, often astroturfed by the clerisy itself, and always demanding more power for the state. They are not suppressed by the bureaucracy, but pretty openly supported by it, promoted in the press and allowed to run riot—and the rioters themselves are often public servants.
Unions are another bit of illusory opposition to the status quo. Unions in the private sector are mostly hype and window dressing. They cannot do much. Push up the cost of labour, and the company just goes bankrupt because they can no longer compete. Unionize the entire industry, and the industry just moves abroad, to China or Vietnam or Mexico. And the ordinary labourer is screwed. It only works for the clerisy. Seventy-six percent of public sector workers are unionized in Canada. Only thirteen percent in the private sector are unionized. The clerisy, with their unions, make a show of negotiating with themselves for better conditions, more power, and higher wages at the expense of the general public. Because they run a monopoly, they can get pretty much whatever they want.
The left pretends to be for the little guy, but shows open contempt for those who work with their hands, the working poor. They call them “rednecks,” “hillbillies,” “clinging to their guns and religion,” “deplorables,” “an unacceptable fringe.” They mock them in characters like Archie Bunker.
And they work against their interests. Mass immigration is the program of the left. This is obviously against the interests of the working poor. More competition for jobs, driving wages down. Minimum wage laws are also directly against the interest of the poor, forcing them into welfare by denying them the right to work, and into permanent dependency on the clerisy.
The clerisy, the “experts,” the bureaucrats, are the scribes, Sadducees, and Pharisees Jesus unambiguously condemns in the Bible.
