If you're genuinely asking: when companies get controlled by greedy people then morals take a back seat compared to financial gain (for those people). The greedy people have the money, they can structure society using the power they have because of it, they can corrupt others (who are also greedy) to support them. The people whose ancestors weren't as greedy, or lacked the violent capabilities to satisfy their greed, lack the resources to oppose the greedy. The greedy people get rewarded with more power to continue being greedier; they pass on their moral outlook and power to those who are similarly greedy.

The pattern seems to be that after a lifetime of wealth acquisition one buys a cloak of respectable benevolence by donating a fraction of that wealth to good causes (which you'll probably carefully choose to provide the best tax benefits and as a marketing tool to help the next generation of super-wealthy to get a good start).

Any company prepared to be sold off, if profitable, will be acquired by greedy people.

People who want a quiet unassuming life living in harmony with those around them don't acquire the wealth in the first place, they have the morals to run companies for good, they don't have the wealth to acquire them.

Capitalism appeals to [immoral] greed, it's a natural successor to feudalism.
