I think there are probably many more things besides pre 1978 wall paint that have lead in them. What is the point of getting all excited about the paint? Lead awareness has increased and we are starting to see products with a "lead free" label on them. I would assume many of these products before you started seeing the labels may not have been lead free or at least not verified that they were lead free.
Since 1978 all products that might be nibbled on by small children are required to be lead free. The list has certainly expanded since then. Now lead is almost by permission instead of exclusion.
The point of the thread is that pre-1978 homes are still very common. A contractor working on a pre-1978 home will have to get certified by the EPA. If he doesn't then he'll have to stop work if the area expands over 6 sq ft or requires a banned technique. This effectively means that any established contractor takes the classes and only independent handymen ignore them. It also means that a certified contractor will usually have to use lead-safe work habits on all pre-1978 homes even when not required. This is extra cost.
The EPA claims to be doing this to protect children. 250 million homes still exist from pre-1978. They are primarily occupied by low-income residents. An estimated 64 million of these homes have children. Despite the claim to protect children, there is nothing in the provision to fix the homes by eliminating lead. The effect of the EPA ruling will increase repair costs for these homes thereby making housing less affordable to the working poor.
The EPA ruling also affects the poor through rental rates. Pre-1978 rental units are primarily low-income. Yesterday they would watch a repair; Now they probably have to leave the residence. Yesterday the contractor would casually repair the wall; Today the contractor moves the furniture, lays sheeting over the furniture and floor, hooks up a fine filtration vacuum, wears PPE, and avoids labor-saving techniques to make the same repair. Repair rates in pre-1978 homes shoot up; thereby rental rates increase to cover repair expenses; thereby low-income poor get hit with the cost.
The prior EPA ruling was bad enough. It also claimed to protect the children. Tenants and buyers have to be notified when buying a pre-1978 house that it
might contain lead unless the seller or landlord has a lead-free certification done. Duh! It's a pre-1978 home! They ALL contained lead! But if you don't tell them this common knowledge the EPA will fine you $1000.00 per day. What they will NOT do is require you to eliminate the hazard.
The bottom line is that the EPA is doing nothing substantive to protect children. Rather by creating classes and fining violators they have created a new revenue stream for the EPA (government). The lack of remediation preserves the tax revenue from drying up. The tax falls primarily on the working poor.
