You are a common liar and demagogue. Just look at Apple's market shares in the US in the smartphone market. And on the market share of Windows in the world, which has long grown into a market dictatorship for more than 20 years. Or Intel's market share and criminal practices in the US and the world. Etc. and so on. The US antimonopoly authorities and officials are completely corrupt, as throughout the world, because deliberately for geopolitical reasons, they diligently do not notice direct violations of antitrust laws by large corporations.
They are too important to influence in the world to be forced to split apart. It is much easier for dirty politicians and corrupt high-ranking officials to have behind-the-scenes dealings with the leaders of one large company. And it is much easier for a large corporation to influence them. The system becomes self-dragging into a criminal conspiracy of all participants in secret, behind-the-scenes transactions.
All countries of the world have long been ruled by organized criminal groups, and the owners of large companies themselves gradually become those who rule the world through secret criminal connections with these groups.
The population are stupid sheep who believe in "democracy", "elections", "the judicial system" and all that kind of nonsense, which in reality is a carefully constructed circus for suckers. A public front facade covering the world of real dirt and evil.
And so that all these creatures could exist with impunity, they came up with "offshore companies". And when they became too dangerous, they came up with "cryptocurrencies" to continue effective corruption and embezzlement.
The Chinese and Russian kleptocracies have long been tightly intertwined with the Western ones, as well as the kleptocracies of other countries. This is the same criminal group. The stupid population does not see the forest behind 2 pine trees.
Marx threw out the slogan "Workers of the world, unite!", but it was heard not by stupid workers of all stripes in the world and not even by the "middle class" that grew out of them, but by kleptocrats in all countries. And in 2020 they delivered their first united blow to rights and freedoms, testing the strength of civil society and its rationality and ability to adequately respond to evil. They (kleptocrats) won this round, became convinced that the power of civil activists is no longer enough to bring some sense to the increasingly dumb majority of the population, and continue to win round after round. While the stupid majority of the population (and in a democracy the majority wins elections, even if it is stupid and easily manipulated!) with open mouths, in shock or with stupid approval (for the sake of the ephemeral "security" thrown into their heads) watches as one chain is thrown over them after another.
Well, such a civilization will eventually devour itself. And it serves her right.
