Lawmakers face the same problem in that they're barraged with constant problems from completely different fields that they're unlikely to be subject matter experts in. How do they learn about it? By consulting subject matter experts. Who are these subject matter experts? Well established businesses in their field. This can lead to laws that are incentivized towards large businesses. That's just considering a situation where everyone is working in good faith.
Now consider lawmakers having to cater towards what is currently trending with the populace, kickbacks from companies, pull from different governments/organizations/political parties etc. And it's easy to see why politics is the way it is.
